[Bug 675965] Re: 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 from the timeframe of the error. https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/675965/+attachment/1736127/+files/10.10.2.log -- Apache crashes with glibc detected and stack trace https://bugs.launchpad.net/bugs/675965 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

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 https://bugs.launchpad.net/bugs/675965 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 675965] Re: Apache crashes with glibc detected and stack trace
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 with the core code. The only thing I can think of is that I can look at Apache's other_vhosts_access.log on the server and try to work out what Moodle was doing at that time, or a few minutes before. I will do this tomorrow as I am not able to access the logs right now. -- Apache crashes with glibc detected and stack trace https://bugs.launchpad.net/bugs/675965 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

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.

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'.

I have just realised that having updated/upgraded, I may have 1. solved the problem (you never know) and 2.

Have run apport-collect on the server via a remote ssh session but despite trying to sign in with my email address and password (good text interface by the way), the continue text is inactive. I can get a forgotten password, create a new account or cancel (all work) but I cannot continue. Have never used this before so it's possible I'm doing something wrong, but I can log in just fine to Launchpad via a browser on my desktop machine. -- apache crashes with *** glibc detected *** /usr/sbin/apache2: double free or corruption (fasttop): 0x7f8b5c8fdac0 *** https://bugs.launchpad.net/bugs/651134 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to apache2 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
