Created attachment 348336 [details]
Script for coredump analysis
just run the attached script with the core dump file, like
gbt firefox core-file-name
you will get a file firefox-backtrace-number.txt. Please attach it to this bug report.
Thank you
I've since updated to firefox 3.0.11, so I can't trivially run your script on this system. I think I should be able to run it in mock, or with a liveusb+updates with a little work and the 3.0.10 rpms. But I can't see what information this script provides that /usr/bin/pstack doesn't. Dont' bother ... if you won't be able to reproduce the hang, somebody else will. I will give you a month, and if you won't be able to provide more detailed backtrace, only then I will close this bug. Can you tell me what is missing from the backtrace in attachment #347822 [details]? I prefer to reach for pstack than gdb+typing to get a backtrace from a running process, since it's possible to send the output to a file. So I'd like to know if and why pstack loses detail. Both pstack and attachment #348336 [details] are gdb scripts, pstack just suppresses most output before 'thread apply all bt', and that seems to be mainly symbol loading. Note: Attachment #341454 [details] contains a kded4 backtrace I made with gdb for another bug. I can't see any substantial difference between that backtrace and the one attached to this bug. But maybe I'm just lost in the noise? (In reply to comment #2) > I've since updated to firefox 3.0.11, so I can't trivially run your script on > this system.

No, that's OK unless you are able to reproduce the issue with the current upgraded version of Firefox. If yes, then we would love to see new backatraces.

Unfortunately not only. In you gdb backtrace you have also the line 0x00554416 in __kernel_vsyscall () saying where actually was the processor in the moment of stopping the firefox process. This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
Created attachment 347822 [details] pstack of hanging firefox process Description of problem: Firefox has been hanging/freezing a few times in the last few days, which is unusual here. The most recent time I captured a backtrace with pstack (attached). I see the java plugin is mentioned in the backtrace, could that be relevant? I don't think that I visit a lot of java-related sites, perhaps I can narrow down which I used recently. I also dumped the core before I killed firefox, in case there's any useful information to be extracted from it. Version-Release number of selected component (if applicable): firefox-3.0.10-1.fc10.i386 java-1.6.0-openjdk-plugin-1.6.0.0-18.b16.fc10.i386 nspluginwrapper-1.3.0-2.fc10.i386
