Attached patch Reverts max cxns back down to 30. (obsolete) — Details — Splinter Review

Ugh. Increasing network.http.max-connections from 30-256 (bug 648570) seems to be causing ugly hangs for quite a few users: https://support.mozilla.com/en-US/questions/881844#answer-255018 112 reports already since 7 released. Attached patch reverts max cxns back down to 30. (Anecdotally people seem to be reporting success with up to 48: I'd rather play it safe for now).

Comment on attachment 564990 [details] [diff] [review] Reverts max cxns back down to 30. This is a one-line prefs fix for a bug with very irritating consequences (hangs browser and/or consumes lots of CPU indefinitely) that seems to be happening with some frequency.

Comment on attachment 564990 [details] [diff] [review] Reverts max cxns back down to 30. I think this is bad knee jerk engineering decision at this early phase in the release cycle given that noone has made any effort to investigate the issue or publically enumerate the pros and cons. The other instance of this in bugzilla, bug 681198, was determined to be a dll problem caused by the speedbit video accelerator dll. Let's collect DLL information from other people exhibiting the problem. Maybe the blacklist is a better solution. Reverting this change will regress pageload performance - for certain on plus.google.com and I suspect on nytimes.com and facebook.com. I've seen all of those cites shard to acheive parallelism greater than the old limit of 30.

Folks, Thanks so much for the info. We really hope to get this fixed ASAP, and your help is invaluable. Just to make this bug legible, if you could post your DLL list, about:support, and HTTP logs as *attachments* (see the "Add an Attachment" link on this page) instead of cut-and-pasting them into the comment field, that would be great (maybe put your username in the file name: ex: "JohnDoe-DLLs", etc. And in case it's not clear: we need as many reports as possible, so that we can see if there's something in common in your setup that points us at the cause of the problem. Thanks! Jason

Maybe users should also post which security software (firewall) they use and their connection speed and maybe their ISP because a slow connection will more easily expose a problem if a large number of connections are open and possibly cause received packets to get dropped that require to request them once again. Some firewalls may also have a problem with handling such a large on open connections.

My daughter still runs FF 3.6.23 and has not been experiencing problems. One box on Windows 7, one on Windows XP Pro SP3, and one on Windows XP home SP3 running the 5 and on branch (all currently at 7.0.1) have exhibited variations on the high resource usage and lack of responsiveness.

Hi Jason - Here is some additional data for you. Hope this is what you are looking for. I am running the Beta of 7.0 on a 64bit Windows 7 machine. My network.http.max-connections was set to 256 when my normal hang loading Gmail occured.

We'd love to help here, but with the information currently available and some testing around, we haven't been able to reproduce the problem in the QA lab, some of which has software installed that in the past has caused problems, like antivirus software. I'll add the qa+ entry to keep track of this.

I cannot reproduce the issue on vista or linux - but I have created a page that will consistently use 240 connections. http://www.ducksong.com/mozilla/692260/index.html Would anyone, especially reporters of the bug, please try this so we can see if there is a consistent reproducable case here? The page loads 240 distinct img urls using 40 different hostnames. (it happens to be the same image, but it has 240 names.) Given the default parallelism of 6 per hostname this gives the potential for 240 simultaneous connections. The image actually injects a 3 second delay halfway through serving it in order to make sure all the connections have time to establish themselves. I've confirmed it opens 240 connections active simultaneously (I've confirmed from both the client and server sides) so we can see if there is a direct correlation between doing that and the hang some people are seeing. If there is, we can start figuring out what is different between those folks and the works-for-me crowd.

I'm using a Motorola Surfboard - SB5101U - cable modem and a Linksys Wireless G - WRT54GL v1.1 - Broadband Router. Modem is connected to Comcast cable in Tucson, AZ.

OK. I retried this, using the smaller image (in safe mode). FF still hung. Task manager still showed about 2 GB memory / 55-60 percent CPU usage. But FF didn't seem to be completely dead. I could select other tabs, etc. But then FF did, indeed, crash. And it seems to have generated a crash report: https://crash-stats.mozilla.com/report/index/bp-76795978-5ff8-49a8-bbcb-b7bfc2111013 (In reply to Patrick McManus from comment #39) > > retry? http://www.ducksong.com/mozilla/692260/index.html

Just to note, the Modem issue would be a fringe case, but i doubt it would cause high memory and cpu usage, unless it was one of the USB type modems. it could be local drivers however, so updating WIFI/Ethernet drivers might help.

Danial, Yes, I suspect the modem/router issue should stay in the other bug you filed. Patrick: we should probably file a new bug for the crash people saw with your "fat" image page? Presumably not as important as this bug, but still a crash. (or are we ok with OOM crashes, assuming that's what it is?)

What's the status of this bug? I'd like to get it in or get some kind of fix. Hangs/Freezing/not responding is about half of our top issues right now. I can't say that all or even most of them are caused by this bug but we know that for some set of users, dialing back this preference solves (or masks) the problem. Has it landed in beta? aurora? are we doing more investigation and is there a hard time limit by when we'll have to make a decision and take this as a fall back?

My machine does not often hang, it does however have problems on the above test, it either times out or does not complete loading. I will try again after reducing the prefs setting.

@cww: we'll definitely land the pref fix in beta/aurora before the next fork if we can't figure out a real fix soon.

I'm not using any firewall or antivirus software. Ethernet is a TP-Link TL-WN781ND Wireless Adapter, driver is version 7.7.0.329, dated 06/03/2009, from Atheros Communications, Inc. (In reply to Danial Horton from comment #46) > It would be good for those experiencing problems to not only list firewall > software but also antivirus software with packet scanners and the ethernet > card/driver in use.

(In reply to Jason Duell (:jduell) from comment #48) > @cww: we'll definitely land the pref fix in beta/aurora before the next fork > if we can't figure out a real fix soon. if we're forced into that I think the pref should be set to 64. Everyone who has tested that has reported success at that level - and it is enough to accomodate the max levels of parallelism I've seen on a single page. (Although it is worth nothing that chromium went from 100 to 256 with the comment that 100 was not enough in the field - this isn't an academic need.).

We'd have to trace this better to find that actual call that generated this, but that error translates to a few winsock errors, including: ERROR_INVALID_USER_BUFFER ERROR_NOT_ENOUGH_MEMORY WSAENOBUFS ERROR_OUTOFMEMORY All of which point to resource starvation.

Dave, looking at your support info, looks like you are running XP with a nice video card. Curious how much ram you have installed and how much free space you have on your main (swap) drive?

If someone in addition to Dave Jordan (thanks Dave!) could do the logging experiment from comment 65 that would be very helpful. I want to confirm the problem is also in pr_poll in more than one log.

Following the Paged and Non Paged {pp; line of thought, theres actually a glitch in XP where it fails to allocate enough to the pool when lots of memory is available. You will need Process Explorer and the debug symbols set to get the current and limit amounts. Gigabit and Wireless N drivers chew heavily into the non paged pool, but this wouldn't explain the same/similar thing happening on windows 7, which can use 2/2 or 64/4 PP/NP depending on if you have 32bit or 64bit.

Dave, thanks for all the help so far. I have a build at http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/mcmanus@ducksong.com-5cfe77828240/try-win32/ that I am hoping you can try out and send the http log for. Basically at startup time it takes the number of sockets that it thinks you can support and tries to allocate sockets for them and do a poll on them (without connecting them to anything). If they don't all succeed it scales that back to a number than it can work with. This is consistent with the error you were seeing in PR_POLL. My copy of xp confirms 550 available sockets (550 is the max the stack ever looks for). (the http setting is always <= the total socket number.) If nothing else, it would be helpful to see the log.

I can update the pre-test to poll for R|W which is what your real loop is doing when it fails. Maybe that will detect it. If not, then it probably requires the sockets to be connected which we probably can do with localhost or something, but I'd rather keep as a backup plan for now as it seems like it could have complications. I'll update to the R|W version and beg you to test it when its built :) > > Nonpaged 44 MB > Nonpaged Limit 262 MB > Thanks for this - that pretty much rules that out.

(In reply to Dave Jordan from comment #85) > > Hmmm. This one worked - no hang! Awesome. The patch dynamically figured out you couldn't handle the full socket pool so it limited you to 50 (which tested out ok).. I bet you could have handled 63 or 64 but it tests at 50+32, 50+64, 50+96, etc.. it will never go below the value of FF 6. The same patch also lets my windows machines go to 550 sockets. (of which the http 256 connection config option further limits it), which is exactly what we want to see. So that works for your problem. What we don't know is if you have the same problem as the other reporters.

Comment on attachment 568025 [details] patch 2 Great work tracking this issue down, Patrick. I hope we can get more users who've had issues to try your build out--I'll ping a couple of them.

Something like this perl script: #!/usr/bin/perl $gMaxCount = 550; $delta = 100; while ($gMaxCount > 0) { print "$gMaxCount ($delta)\n"; $gMaxCount -= $delta; $delta = 32 if ($gMaxCount < 200); $delta = 30 if ($gMaxCount < 150); // just so we hit 64 $delta = 8 if ($gMaxCount < 100); } That gives us this sequence: 550 (100) 450 (100) 350 (100) 250 (100) 150 (32) 118 (30) 88 (8) 80 (8) 72 (8) 64 (8) 56 (8) 48 (8) ... I wonder if we should set SOCKET_LIMIT_MIN to 48, since we've seen at least one user seems to find that's the magic number to not see this bug happen? We don't really have anything but anecdotal data :( My main issue with the existing code (not your patch per se, but seems we ought to fix) is that is doesn't look like HTTP leaves any wiggle room for non-socket FDs if we have a low gMaxCount. AFAICT we init nsHttpHandler.mMaxConnections to 24 in the constructor, then read in whatever value is set for http.max-connections, clamping it to nsSocketTransportService::gMaxCount: http://mxr.mozilla.org/mozilla-central/source/netwerk/protocol/http/nsHttpHandler.cpp#844 We should really only ever take a % of the total FDs available, right? How badly do we behave if we try to open 64 (or whatever's the max) HTTP cxns while we have some FTP cxns open? If we perform ok in that situation, then we stil have the issue of leaving enough FDs for regular files. (Do non-socket FDs matter on windows for select/poll? If not, and we handle the FTP issue ok, then this issue is moot).

Attached patch Lower max HTTP cxns down to 48 for Windows only. — Details — Splinter Review

I've personally emailed a bunch of users to try to get more data about whether Patrick's patch fixes the issue for them. Even if we hear back from them, at this point, I think we should land the simple, bulletproof pref change on beta and aurora. If we're confident we've got a fix soon, we can hopefully land that on aurora, and otherwise let it bake off m-c. I've changed the pref limit to 48 (not 30), since everyone on the newsgroups reports that that works. I've also made the limit Windows-only, since we have no reports of problems elsewhere.

This is same idea as patch already approved for aurora/beta, just limits the patch to windows (no need to reduce perf on platforms that aren't affected) and bumps pref to 48 as that's been a safe workaround for all users we've seen so far.

Attached patch patch 4 — Details — Splinter Review

To avoid the Ts hit, do the active probing only when we hit 30 active connections for the first time. I used 30 (instead of 48, 50, 64) because it is the historical-never-had-a-problem http limit. So it will only kick in when things are really busy anyhow - a few milliseconds won't be felt in the middle of that frenzy. It does complicate the code a bit.

I may be running into this problem at home. I recently dusted off an old router after contracting new internet service, and I've noticed both Fx and Chrome will stop being able to connect to a site (not hanging) and power-cycling the router fixes it. I'll test the tryserver builds here and see if there's a difference.

Its marked fixed because we're not aware of anyone with this problem, until now :) Can you load a clean profile (or at least reset that to 256), and start firefox with http logging https://developer.mozilla.org/en/HTTP_Logging to generate the error and then upload the log. We can triage that.

Huh, that file submission procedure didn't quite go as I expected. That's supposed to be a RAR file. The actual log is about 400 MB large. A correction: I didn't actually experience this bug for years (I realized, after further thought); it was more like months. Maybe one year, maybe less. The bug was easy to reproduce. I switched the HTTP max-connections setting to its default (256). I opened three tabs to three random-ish web pages that looked to have lots of clutter and **** on them; it doesn't seem to matter all that much which sites they are, but the particular three I used here were: http://www.ghirardelli.com/about-ghirardelli http://www.urbandictionary.com/popular.php?character=S http://www.gilt.com/sale/women?variant_regwall=current&pkey=womendisplaymisc&opaid=akamai&utm_medium=paid%20display&utm_source=akamai&utm_campaign=GS:Women:Display:akamai&utm_content=GS:Women:Display:akamai:acquisitions I switched through the three tabs over and over, clicking one random link on each page's top menu bar as I passed. In general, a page would finish loading before I reached it to click the next link in that tab--until the bug arose, of course. After what felt like a minute or two, the bug became evident. All three tabs appeared to get stuck in the process of loading things. Firefox remained responsive, but would not load anything further until it was done doing whatever it was doing. My CPU has three cores; one of them was fully occupied during at least some of this time. During this time I opened a couple of the links Firefox was struggling with in another browser, and they worked fine. After what felt like a minute or so (I can try again and track the events more precisely if needed) Firefox finished whatever it was doing and I think it even loaded all the pages it had been trying to load. I think it worked well immediately after that.

Jeff Quigley

Comment 133

Oh and I also tried the same reproduction strategy with max-connections at 48 and after a few minutes Firefox was still working well enough so I gave up. I still suspect the problem actually can arise with the lower setting, but I could be totally wrong about that.

Multiple issues meaning I'm adding a new one? This bug's Description links to https://support.mozilla.org/en-US/questions/881844 which talks about a problem that sounds just like mine. Maybe some aspect of it was fixed, but my experience seems to indicate that I'm reproducing this report's original bug, and that on the whole that bug was left unresolved.

Sadly I have the same attitude from dev's in anothe rbug report, they dopnt like to admit they have not actually fixed bugs. I think they never did fix it, the proper fix was to undo the change they made that broke FF on windows. Whats shocking is I have seen several code changes made without proper testing, the max connections to 256 was one such change, yet then there is barriers put in place to prevent the changes been reverted. When code is changed and a bug is introduced unless that bug can be squashed immedaitly the proper logical path to follow is to undo the change, in other words lower the default value. Now I have been running a lower max.http limit for a while but I cannot remember what value I was using, about a week ago I reset it to the default and since then I have had to restart firefox 5-10 times because it hangs on either "looking up domain.com" or "connecting to domain.com" on all tabs. I have just dropped the limit now to 48 after a bit of research. What is the habit of refusing to cancel out changes for the windows platform? the developers seem too focused on linux and android. No I am not making a new bug report, you have your feedback it is not fixed, you can carry on shutting your eyes and pretending you have no such feedback but it doesnt change anything.
