ksoftirqd_cpu0 hogs CPU

Slackware 9.1
Problem #1: Every other hour ksoftirqd_cpu0 wakes up and consumes all
of the CPU cycles for 5 minutes. The machine stops serving web pages,
serving files, and sometimes my SSH connection is dropped. Google
searches don't turn up much here.
Problem #2: Apache 2.0.47 uses cronolog 1.6.2. When you restart
apache, it doesn't tell it's cronolog/process children to die.
Consequently, apache restarts, spawns new cronolog processes. There
are 22 idle cronolog processes running on this machine and it seems
that the only way to only solution is kill -9 or a restart.

Does anyone know how Problem #1 could be related to problem #2?
