cron jobs seem to get stuck. Not always, but within a day, there are at
least 20 stuck. It is not always the same cronjob that does the
sticking. :) When this occurs, I can run ps ax| grep cron and get a
bunch of lines like this:
51921 ?? D 0:00.00 cron: running job (cron)
51922 ?? IVs 0:00.00 cron: running job (cron)
52544 ?? D 0:00.00 cron: running job (cron)
52545 ?? IVs 0:00.00 cron: running job (cron)
54418 ?? D 0:00.00 cron: running job (cron)
54419 ?? IVs 0:00.00 cron: running job (cron)
54667 ?? D 0:00.00 cron: running job (cron)
54668 ?? IVs 0:00.00 cron: running job (cron)
55835 ?? D 0:00.00 cron: running job (cron)
55836 ?? IVs 0:00.00 cron: running job (cron)
What is going on? Please help me remedy this situation.
The PID numbers next to cron's with a STATE of "IVs" show up in
/var/log/cron, for example:
# grep 54668 /var/log/cron
Dec 2 22:32:00 pita /usr/sbin/cron[54668]: (root) CMD
(/root/bin/raid-status.sh CRON)
# grep 55836 /var/log/cron
Dec 2 22:40:00 pita /usr/sbin/cron[55836]: (root) CMD
(/root/bin/10minutes.mail.sh | mail -E -s "[ERROR]
mail.monkeybrains.net" [EMAIL PROTECTED])
If I run 'lsof' I can find these open handles:

What is going on? Is my libnss_mysql acting up?
