To avoid the problem of jails all starting things at the same time, use the cron(8) flags -j and -J to set a 'jitter' which will cause cron to sleep for a random period of specified duration (60 sec max). Cron flags can be set using the rc.conf variable 'cron_flags'. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
