I can't determine which cron job is causing the CROND malfunctions. 
Even 'ps -faxlwww' shows CROND with no arguments as the command.  Now, I
see by experiment that when 'crond' spawns a job, it forks a copy of
itself called CROND which, in turn, runs the cron script as a child.  If
the child core dumps, does that result in another CROND process which
dumps core?  Or is the CROND process itself dumping core?
