Have you added anything particular to /etc/crontab?
How about any crontab(1) files stored in /var/cron/tabs?
Any files in /var/at/jobs or /var/at/spool?
atrun(8) should only be invoked by cron(8).
at(1) is the user interface to the atrun service.
Unless you or your users need the atrun service, you could simply add
the # character at the beginning of the atrun line in /etc/crontab.
There's no need to restart cron(8) after editing /etc/crontab, on the
next minute cron(8) will notice the change in timestamps and re-read
/etc/crontab.
Now, in your case I would first try and understand why you have so
many cron processes running,
ps -adux
would be helpful, and next kill them all using
killall -TERM cron
, and if failing that, kill them using
killall -KILL cron
Delete any files in /var/at/jobs and in /var/at/spool.
Finally, if you're convinced your /etc/crontab and any files in
/var/cron/tabs are sound, then start cron again using
/etc/rc.d/cron start
