>Description:
cron suddenly stops, it prints nothing to log and does no jobs. It didn't crash.

We didn't change any config files or so, it stopped (went to sleep) at early morning (we have last record in "cron" log at 05:33 AM).
Noting strange is in "messages" log around that time. There is no other system problems except cron. Since upgrade the problem has happened only once.

Running "/etc/rc.d/cron restart" helps.
