OK, the problem happened again and I was able to pull some information
from server-status.
First of all, here's the appropriate part of my config:
MinSpareServers 3
MaxSpareServers 5
StartServers 3
MaxClients 50
MaxRequestsPerChild 30
I've attached a few files:
* server-status.normal.htm - the output from server-status during
normal operation
* server-status.problem.htm - output from server-status as soon as I
detected the problem
* server-status.problem.escalating.htm - output from server-status a
few minutes later
* process.list.txt - output from ps -ef|grep apache during the problem
As you can see from process.list.txt, Apache is completely ignoring
MaxSpareServers and creating a ton of child processes until it
completely runs out of memory. Sometimes it gets in this state a
couple times a day, other times it will go for 10 days without the
problem occuring.
Any idea what is going on and how I might be able to fix it or
troubleshoot further?
Thanks!
Dave
Whoops. process.list.txt was an empty file in the last email. Here's
the contents.
