klogd and syslogd high load usage

[Danny Terweij - Net Tuning | Net]

On a system (FC3) the load usage on klogd and syslogd are very high and
running all the time.
I have reniced them to 19 and system loads gets back to below 1.00 and stays
stable. The box was last week 1 hour not reachable because those 2 produced
a (last known) load of minimal 600.

The logfiles at /var/log are not big. and most ones are weekly rotated. I
guess syslogd is doing things for /var/log.
But what is klogd doing?

The only big logfiles i know in this system are logfiles from apache (a lot
virtual hosting domain names).
These apache domain-logfiles rotates also every week.

So do I need some tweaking/tuning somewhere?
