[Bug 675965] Re: Apache crashes with glibc detected and stack trace

2010-11-17 Thread Paul Vaughan
It may be worth mentioning that I filed a very similar bug to this one within the last month or so, but as it was closed as 'cannot reproduce' or similar and I cannot locate it to link to. It definitely had 'glibc' in the title of the report. -- Apache crashes with glibc detected and stack trace

In Apache's error.log, the error happened at some point between 10:00:39 and 10:01:18, so I have included a much-reduced access.log with all PHP files executed between those time points on that day, appropriately sanitised. Hopefully it will prove useful. ** Attachment added: "Apache access.log fr

Hi Mathias. You are correct, the server runs PHP scripts, but as part of the open source VLE Moodle: http://moodle.org/ Moodle is a complex application and I would have no idea what aspect of it might have caused apache to crash. I develop code for Moodle, but plugins only, I have little to do wi

Hi James. At this time, with the latest build of Apache as mentioned in my last post, I'm not seeing this issue any more. I'll open a new issue if I do see it again. Cheers, Paul. -- apache crashes with *** glibc detected *** /usr/sbin/apache2: double free or corruption (fasttop): 0x7f8b5

Hi Christine. Since upgrading Apache to 2.2.14-5ubuntu8.2 we haven't seen this issue resurface in over a week. I've also noticed that 2.2.14-5ubuntu8.3 is available so may tentatively upgrade to that. I hope that's of some use. Paul. -- apache crashes with *** glibc detected *** /usr/sbin/apach

I have gdb running on the server, but as I have no idea what causes the error I'll just watch Apache's error log until I see it print out the backtrace and memory map. -- apache crashes with *** glibc detected *** /usr/sbin/apache2: double free or corruption (fasttop): 0x7f8b5c8fdac0 *** htt

After approximately 2 days of normal use, the error has not reoccurred (whereas normally we'd see it approximately 3-5 times in a 24 hour period). I guess we can consider this issue 'gone'. Cheers. -- apache crashes with *** glibc detected *** /usr/sbin/apache2: double free or corruption (fast

Thanks for the above, it worked successfully. I will keep a close eye on Apache today (a normal day's use, basically) and report back. Regards. -- apache crashes with *** glibc detected *** /usr/sbin/apache2: double free or corruption (fasttop): 0x7f8b5c8fdac0 *** https://bugs.launchpad.ne
