Below is part of the cron... Seems like any random cronjob can get clogged up... load varies from 0.2 to 1.0 on this dual-core box. I rebooted the box -- cron's continue to slowly pile up. One of the cronjobs that is 'stuck' is this one: /root/bin/raid-status.sh which can be found here: http://www.monkeybrains.net/~rudy/example/raid_status.html Forgot to mention, I am running: 6.2-STABLE FreeBSD 6.2-STABLE #3: Thu May 31 01:18:15 PDT 2007 OH, ps shows this: 58383 ?? D 0:00.00 cron: running job (cron) 58384 ?? IVs 0:00.00 cron: running job (cron) /var/log/cron has this entry: Dec 3 20:16:00 pita /usr/sbin/cron[58384]: (root) CMD (/root/bin/raid-status.sh CRON) BUT there is no 'raid-status.sh' stuck in the "ps axw". Seems like the vfork set off the cronjob, it ran, but then cron didn't 'stop' executing. Any debuggin tips?
