I saw this too - same setup as yours (2.2.x, smp, Sq2.8, VNC). It went
away some time ago, now CPU usage is less than 1%. Unfortunately, I do not
know what I did to cause that ...

Anyway, I just upgraded to RedHat 7.0, and it's still fine. I'm seeing
peaks in regular intervals (every 5 minutes or so) and I haven't figured
out where these come from
