We have an issue with a dedicated server load.

We have 16 processors with 4 core @ 2.40GHz, if I understood correctly cat /proc/cpuinfo output.

Unfortunately, I don't have access to free -m or vmstat.

But from top I got that we have 24 GB.

And snapshot from top about processes:

As far as I see, memory is not used at all. But the cpu is used heavily. Apache consumes most of CPU. 

Another useful piece of information:

Every 1.0s: ps u -C httpd,mysqld,php                                                                                                                                                                                                                                                                                                           Tue Mar 27 10:48:19 2012
