im experiencing patchs of extreamly high load on a server,

ive looked at the cpanel account usage and this seems inconclusive to whats is causing the high load.

i put together a little script to log the load once a minute http://www.web-tiger.net/log/report.php is the result.

When load is high i get 99% iowait and kscand is using a lot of cpu, currently as i write its used 25:06 mins of cpu time, which seems quite high

The only reference i could find to such a problem is https://bugzilla.redhat.com/bugzilla/show_b...g.cgi?id=100680
however this seems to of been fixed in a previous kernal

So any linux gurus got any idea?
also their is only a few sites on this box, non are very heavy, althoguh 1 invision forum is quite big but still should not be causing spikes as seen in the above graph.
