This signature still garners a fair amount of crashes per week: https://crash-stats.mozilla.com/report/list?signature=fastcopy_I The user in Bug 656612 seems to hit the crash pretty frequently.

It is #93 top crasher in 6.0 and #11 in 7.0b1. There's no longer a correlation with RealPlayer in 6.0 or 7.0.

we were averaging about 750 crashes per day for this durning july. now averaging around 920 over the last 30 days.
distribution is across many releases but it does look like a volume regression some where along the path in the recent releases. firefox 7 has almost as many crashes per day as firefox 6 with substantially fewer users.

Something definitely regressed here. I looked at some data on 7.0 beta compared to 6.0 beta. We are getting about 105 to 200 of these on release versions ie: 5.0, 6.0. for 7.0 beta we have over 200 a day. During 6.0 beta we had about 50 a day.

It's #3 top browser crasher (w/o hangs) in 7.0b2.

The crash ratio between 7.0 (about 3000 crashes/week/1M ADU) and 6.0.2 (23 crashes/week/1M ADU) is about 130. According to crash stats in Firefox 7 Aurora: https://crash-stats.mozilla.com/report/list?signature=fastcopy_I&&range_value=4&range_unit=weeks&version=Firefox:7.0a2 the regression range for the spike is: http://hg.mozilla.org/releases/mozilla-aurora/pushloghtml?fromchange=bcd26d45856a&tochange=d80597c09388 bug 678588 changed singleDeviceInterval from 24 hours to 1 hour. It has only highlighted an existing problem.

Comment 15•12 years ago

I've been looking through crash reports and the stack traces for fastcopy are all over the place (because fastcopy is part of the implementation for malloc, realloc, etc on Win32). I have a nagging suspicion we are dealing with a heap corruption, but it isn't obvious where it is occurring (as with most heap corruptions). I'm thinking analysis of the stack straces for common frames would be helpful. The folks in #metrics and #breakpad say that chofmann has a tool to do this. chofmann: can you explain what your stack analysis tool does and help us use it, if appropriate?

We have some other hints pointing at memory corruption introduced sometime this summer; jduell was tracking one last night responsible for ~13% of crashes on fennec that looks like mem corruption, and I've heard a few other anecdotes about hard-to-pin-down crashes pointing there.

I'm currently working on parsing *all* of the crash reports from the last 30 days (from https://crash-analysis.mozilla.com/crash_analysis/) to see if I can find any common patterns, particularly with regards to the stack frames and version numbers. I'll update the bug when I have data.

But, the counts in the unreleased versions are troubling given the percentage of users on those versions. 7, 8, and 9 have about the same number of crashes (7006) as 6.x (8405). Anyway, I don't think there is much new data in this comment that hasn't already been said. Next up, I will be looking at the stack traces for all the crashes (31851 total) looking for frame correlations.

First, I've created some tools to enable easier crash analysis. Code available at https://github.com/mozilla-services/socorro-crash-utils. I've tried to include as much as possible in a Python module, which others should just be able to pick up and import to grasp the power. Anyway, I've fetched ~20k crash dumps so far.

I have ~80k crash dumps with fastcopy_I from the past 90 days harvested on my computer. But, I really don't know where to continue analysis beyond the primitive ones pasted above. If anyone wants me to run a custom report, I can do that (it does take a while to fetch all the data from crash-stats). I just need to know what to run. In hopes of reproducing the crashes, I wrote an extension that surfs the web for you, hopefully generating entropy to trigger the crash. It is kinda hacky, but works well enough: https://github.com/mozilla-services/sync-spray. Unfortunately, after running Nightly for 30 minutes on a Windows box, I was unable to get a crash. I'll keep on it and will hopefully get lucky.

(In reply to Christian Legnitto [:LegNeato] from comment #12) > I backed out bug 678588 For an unknown reason, the backing out hasn't prevented the spike, so it is still #3 top browser crasher without hangs in 7.0b6.

After further investigations, I found that the spike happened in two close times: * a first one at the end of 7.0a2 (see comment 11) that made it #6 top browser crasher in 7.0b1. * a second one between 7.0b1 and 7.0b2 that made it #3 top browser crasher in 7.0b2 and above. The regression range for this second spike is: http://hg.mozilla.org/releases/mozilla-beta/pushloghtml?fromchange=00f56713eab6&tochange=4ee096ccdd5a

It scares me that bug 678422 (the nsPresArena over-allocating clownshoes one) is in that window. If we are dealing with heap corruption, it is possible those clownshoes were buffering us from a minefield of corrupted bits.

Forget about comment 24. It's because #3, #4 and #5 top browser crashers in 7.0b1 have been fixed in 7.0b2 or were startup crashes. The ratio between #1 top browser crasher and this crash signature has been pretty constant along the Beta phase, i.e. about 2.

Here are crash stats from the past 14 days: Build Percentage Count Rank 8.0a2 0.65 145 11 7.0b6 1.03 868 10 7.0b5 0.85 1268 10 6.0.2 0.11 1628 109 According to the mozilla-beta commit logs (https://hg.mozilla.org/releases/mozilla-beta/shortlog/), the backout of bug 678588 was the last commit before 7.0b6 was cut. Unfortunately, the percentage of crashes went down marginally (at least compared to the 6.0.2 0.11% baseline). If the percentage holds up, it looks like fastcopy_I is going to be a top crasher on stable/7.0 starting tomorrow :(

I backed out bug 678588 in beta8 as well. If it is determined we don't need to do that we can reland

Actually, because of this investigation we are going to re-land bug 678588 on beta8.

(In reply to Scoobidiver from comment #23) > For an unknown reason, the backing out hasn't prevented the spike I think I understood. There's a delay to update before the release of a new Aurora version so every crashes in the latest Aurora 7 build were more important than in the previous ones, making think it was a spike. 7.0a1: 20 crashes/1M ADU/day 7.0a2: 130 crashes/1M ADU/day The regression range could be in the changesets between 7.0a1/20110705 and 7.0a2/20110706: http://hg.mozilla.org/releases/mozilla-aurora/pushloghtml?fromchange=cc6e30cce8af&tochange=92120afb1a58

This is pretty far down on the list for 10.0 #64 and 9.0.1 #94. I am going to take it off the top crash list.

Still, this seems to happen only up to Firefox 8, so this might actually just be fixed. If so, we probably should mark it that way.
