Hello,
Over the weekend, I upgraded one of my servers that runs mysql and pdns to 5.3. Previous to the update I have not had an issue form this server. But since, I have had mysql die multiple times from oom-killer.
$ uname -a Linux rack2a 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:10:25 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
Unfortunately, the server has been rebooted by others before I have been able to look at it while the problem is occurring. But I have found this in the logs:
http://pastebin.centos.org/25553
Running sar -A:
http://pastebin.centos.org/25556
Since the server was rebooted, the amount of swap is used is 0.
How do I determine what process is/was chewing up the memory on this server? What should I be looking for to narrow this down?
Thanks, Rick
