Problems with our Sun3/480 hanging...

[Bala Vasireddi]

Can all the people who sent me mail in response to our 'find invoked by
cron hanging the Sun4/380' please resend me their messages. I'm really
sorry about this. My mail spool filled up and I lost all the incoming
mail.

Here is a brief description of my problem:

Within the last 5 days, one of our Servers was hanging every night
sometime between 3.15 am and 3.30 am. This happened 5 out of 5 times.

Intially we thought it might be a temporary hardware glitch and rebooted
the machine. But after it happened twice in a row, we became suspicious
and started searching for other explanations. We checked the cronlog and
determined that the machine was hanging after 'cron' started the:

15 3 * * * find / -name .nfs\* -mtime +7 -exec rm -f {} \; -o -fstype nfs -prune

command. Right now we are 95% certain that running this command (manually
or through cron) on a Multiuser system will hang our System.

NOTE: Running the same command in single-user mode doesn't cause any
problems.

Thanks very much for your effort.
