Like the title says... I have ServerLimit set to 500 and I just noticed that my server has 500 httpd processes running... but netstat only shows 161 ACTUAL established connections.

Since it's hit the configure limit Apache will not accept any new connections, which basically kills off my sites.

Has anyone ever seen this happen before? I don't think it's a runaway script (scripts getting stuck in a loop then eventually being killed off by PHP) because the processes are not consuming a large amount of CPU... they're pretty much all at 0.00%

Everything else looks normal... 1500MB+ free RAM, 0.2% swap used. Nothing reported in the Apache or OS error logs.

Very weird.

Apache 2.2.11, php 5.2.9

Thanks for any hints/tips
