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.
