The system is an HP 715 running HPUX 10.20
From time to time and seemingly without reason, CRON will shut itself down. A look at the log file reveals that its last action was to attempt to execute a job in the crontab at an odd time. I've deactivated, then reactivated the crontab which seems to have helped at least for the time being. The problem with this solution is that I've done this before as a quick fix, but the problem resurfaces after a time.
What could I check to gain a little more visibility into what CRON is doing and when, and how can I prevent CRON from shutting itself down again? What could affect CRON to force it down?
