Description of problem:
The first time I su to root on a given day, /bin/su will consume 100%
of the CPU for 60 to 90 seconds, during which time the system is
almost completely unresponsive. xload shows the cpu load spiking to 7
or 8 from near-zero load before and after. Subsequent invocations of
su that day will perform normally, but the problem always returns the
Given the recurrent daily nature of this I suspected that it might be
related to a bad cron job leaving some garbage behind, but so far I've
been unable to duplicate the problem by running cron jobs during the
day and checking the system immediately after they run.

Actual Results: CPU utilization spikes to 100% for 60-90 seconds on

should return immediately
Please log in as root and run:
