User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050223 Firefox/1.0.1 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050223 Firefox/1.0.1 When I go to http://hubblesite.org/newscenter/newsdesk/archive/releases/ And I select a News releases by year: any year. I proceed to select the images that are astronomical not others like illustration or art. I normally select the high resolution .tif files and if available the desktop wallpaper versions at the size of 1024x768. I also have Download sort 2.5.0 set to filter .tif and .jpg files to a specific folder. What happens is that I started to download every .tif and sometimes .jpg files to a specific folder by right clicking and selecting save image as... in the context menu. When I select the save image as... in the context menu Download Sort 2.5.0 then sorts the files. Then the download manager pops up and then I minimize it. I continue to download file after file concurrently with as many as 16 going on at once. Year 2001 and 2002 gave me the biggest trouble. After downloading for a while Firefox seems to become sluggish, like when I use my Intellimouse Explorer 4.0 wired side keys to go forward and back there seems to be a delay of 1 3 seconds. If I try to save a file a second time then the save as dialog box also is sluggish 1 to 5 seconds. Eventually Firefox or the download manager locks up with 99% cpu usage and with a memory foot print of 245MB or larger up to 260MB. When the browser stops responding I will try to minimize Firefox and look at the download manager and all I see is a white or grey space along with the Dos like icon in the uper left corner. If I try to close the download manager then windows will popup with "this program is not responding" and if I terminate the download manager then Firefox is terminated as well. When I terminate Firefox I lose any remaining downloads or the downloads are corrupted. The cpu and memory claims are taken from Microsoft windows task manager. I will terminate Firefox when this happens and then restart. Then I will proceed as usual but this time I will keep the number of concurrent downloads at 8 or fewer. This seems to help greatly. I also use Tweak Network 1.0 and I have it set to Max connetions 60, Max connetions per server 24, Max persistent connetions per server 24, Pipelining is checked, Pipelining maxrequest 30. Also My Windows XP SP2 global connections limit is set to 500. My ADSL connection is 1.5mb. Reproducible: Always Steps to Reproduce: 1.Go to http://hubblesite.org/newscenter/newsdesk/archive/releases/ and in the News releases by year: box select 2001 or 2002. 2. in the box (Thumbnails: Displays images only) check it. Then at the bottom of the page in the box (Results per page:) select 100. Then proceed to download every .tif file and when available desktop wallpaper at 1024x768 3. Do this as fast as you can. Keep the number of concurrent downloads at 15 or higher. Don't stop until you have gone through all of 2001 and 2002. This should cause your Firefox browser to become slugish and eventually result in a lockup with 99% cpu usage and 245MB memory foot print. You will lose any remaining downloading files or they will be corupted. Actual Results: Firefox became very slugish 2/3 thirds of the way through 2002 and then locked up. I proceeded to minimize Firefox and look at the download manager but the download manager box was all white or grey, my eyes can't be sure. I tried to click the x close button in the upper right coner but Microsoft windows poped up with a box that said "this program has stopped responding" I cliked to terminate the program and it terminated the download manager and Firefox. The remaining downloading files were lost or corupted. Expected Results: Firefox should have downloaded normally. Meaning with a reasonable memory footprint of less than 150MB and cpu usage of less that 75% at least. Firefox should not become slugish. The download manager window should not become a blank white or grey box with a Dos like icon in the upper left corner. Default Theme, Windows XP SP2, 1.8AGHZ Intel P4, 1GB RAM,
I wonder if this might be "Core: File Handling" instead.
(In reply to comment #1) > I wonder if this might be "Core: File Handling" instead. Well I thought it should be download manager because it seems to be fine on fewer concurrent downloads. I might be suggesting that Firefox's cache or pagefile writes are too few in between maybe? Instead of writing the data at regular intervals to keep RAM memory low, it keeps it in RAM too long? Then you have the cpu dealing also with the massive RAM data and just trying to coordinate everything. I thought file handling refered to external programs for certain Internet protocols or on how to handle them internally?
I want to clarify my supposed bug report. When I download the images, specifically (.tif) (.jpg) I "left Click" on the (.tif) files and then "Download Sort 2.5.0" sorts (.tif) into the appropiate windows folder. (.jpg) files I use "left click" which then causes Firefox to begin downloading and displaying the (.jpg) file. However, I do not wait for the (.jpg) file to complete downloading and display, instead as soon as I see a sliver of the (.jpg) file (image) I "right click" select save image as... from the context menu. Download Sort 2.5.0 then sorts the (.jpg) file in the correct windows folder. The key thing is as soon as I have clicked I move on. So I left click on the .tif file then right away I hit the mouses back button etc. Every thing else in the bug report remains the same.
I have what appears to be additional data on this bug. I had to grab a bunch of RPMs from different rpmfind.net mirrors. Eventually, Firefox hung during download; the whole application became unresponsive, and I had to kill it from the Windows Task Manager. Before I did so, however, I noticed that Firefox's memory usage was at about 220 MB, and its CPU usage was at 99%. I kept the task manager open when I relaunched Firefox and started downloading again. Memory usage climbed rapidly as I downloaded more files, quickly passing 70 MB. Closing the Download Manager got me back down to under 60 MB, and reopening it didn't cause the memory usage to spike again, so I would surmise that Firefox is caching the downloaded files in RAM as long as the Download Manager is open. Also note that I'm generally downloading the files serially instead of in parallel. OS is Windows XP SP2, running on an IBM ThinkPad R51 with 512 MB of RAM, Firefox version is 1.0.1.
I have tested Bug 285490 on the trunk build March 15, 2005: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050315 Firefox/1.0+ I still have the same problem as described in bug 285490. I will test "trunk build March 16, 2005" when it is released using the conditions described in comment #4 as posted by Tom Maddox.
Hi everybody, I have tested some more. I tested on March 16, 2005 using the trunk build March 16, 2005 Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050316 Firefox/1.0+ I tried to test like I said I would in comment #5 in response to comment #4 but the site rpmfind.net was very slow it seemed on ftp. I did not test the http download at rpmfind.net. So instead I created a new test again at http://hubblesite.org/newscenter/newsdesk/archive/releases/ But this time I completely erased Firefox from my computer meaning the profile and programs folder. Then I reinstalled the March 16 build in a completely default mode with no extentions. This means I accepted whatever the installer defaulted too, like install locations and packages ect. Then I said no to importing IE favorites. The only thing I changed was in Tools > Options > Downloads > Dowload Folder = save all files to this folder E:\test space . Otherwise every thing else was default install. Then I started to download like I described in the original bug 285490 but this time it took all of the tif files from the years 2002 & 2001 before it hanged. I made sure this install was clean and default every thing except as noted above. I will see if I can add some screen shots using the attachment tool. The screen shots show the hang as well as the read outs of XP Taskmanager tabs Applications, Processes, Performance. I think I have done all I can as a end-user to help the developers. However if you think of something else I can provide let me know! I will continue to monitor supposed bug 285490 and if I ever get more useful info I will pass it on. I just want to say that as a result of all of this I will from now on only be using the nightly trunk builds of Firefox. I have found computing on the edge far too exciting!! I even tried to compile my own build today using the info from http://gemal.dk/mozilla/build.html I failed of course will try again. Thank you. Sincerly Nate Homier.

Nate, screenshots of the task manager are quite unnecessary.
I am very sorry for the attactments. My bad. I tried to delete them but I gues you can't once you upload. No more attachment I promise!
This appears to be a dupe of the download manager history bug. Reporter: Have you tried clearing your download manager history occasionally as you download? Does this keep the RAM/CPU usage from spiking significantly?

Reporter: Have > you tried clearing your download manager history occasionally as you download? > Does this keep the RAM/CPU usage from spiking significantly? Clearing the download manager history appears to have no effect on the memory consumption. Closing the download manager window does cause memory consumption to drop, however.
