apache high system CPU time

Question

I have a web server: ubuntu apache+php app+postgresql and a stats server: ubuntu apache+php - piwik and munin2 installed.

The communication for munin2 is made through ssh.

In munin i see a lot of system cpu activity, that I assume it it because of apache (i see 5 or 6 apache instances using ~5% CPU on top)

I was not having this system CPU activity before.

Does anyone knows how can I see where that comes from?

EDIT: some munin graphs munjin graphs

Check out the TOP command to see system resource utilization.

#man top

Upgrading the kernel and restarting the system should solve the problem.
