[K12OSN] KNotify Problem

[Jason]

Calvin,

I just discovered this on one of our servers using 4.2.  It started on 
Monday morning and continued until I rebooted the server today.

I looked at the processes and quite a few were running for users that 
were not logged in.  The runaway processes were taking a lot of cpu time 
(one was chess at 54% of the cpu time).  I rebooted and the runaway 
processes were gone.  I found a script called maim that is supposed to 
kill processes by the user who started them but no luck so far.
