Server refuses to use swap partition
I am using Linux with Koloxo panel for site management. My database server went down, and I think it happened because of a lack of memory. This is even though the machine has 8GB memory and there aren't many users on the system (maybe about 20 to 50 users maximum at any given time). One thing I see in process is that one apache process is consuming round about 325MB of memory.
Is it normal for the processes to consume this much memory? If not, how can I set reduce the memory consumption per user to a normal level?
