apache memory usage high
We have running ISPConfig 188.8.131.52 with 4 websites installed on CentOS 6.4 with 4GB RAM.
The system is running normal most of the time. Just sometimes, maybe once a month, it ran into high memory use, swapping and then the system is not controllable and we have to reboot the whole server.
If I then check the logs and top, apache seems to freak out completely and using all memory.
Normally the server is not that busy. Maybe 50~100 connections the same time.
Any idea how I can get this solved, or how to debug it?
