Exsessive memory usage.

[joximu]

Linux (or the daemons) always uses as much memory as it can... - why not use memory that is available?

I have a machine with 4GB, 4 sites running, about 60MB free:

Code:

Memory:      Total        Used        Free      Shared     Buffers
Mem:       4031500     3970748       60752           0      573896

of course you have to try to configure the services so they can share the 512MB which is not very much.
Mysql should not use to much (you have to configure this) and apache may use the remaining...
