Hi Gurus,
we're having a BIG problem here:
In the last two nights, our complete network has failed. We're using NIS,
with one NIS-Master and a slave, and NFS to mount the home-dirs.
It seems that every night at 4 o' clock the automountd on all servers stops,
and we're unable to restart it.
The following is a screenshot of what happens when I try to restart the
automountd:

# bash
bash-2.03# /usr/lib/autofs/automountd -T -v
bash-2.03# t1 READDIR REQUEST : -xfn/_x500 @ 100000
bash-2.03# ps -ef | grep auto
root 9774 9729 0 10:29:31 pts/1 0:00 grep auto
bash-2.03#
====================/snap/========================================
As it shows, the automountd does a readdir request to an xfn-dir - and
that's it, its gone...
The content of our /etc/auto_master is:
========================/snip/=================================
# Master map for automounter
#
+auto_master
/net -hosts -nosuid,nobrowse
/home_nfs auto_home -nobrowse
/xfn -xfn
=========================/snap/================================
I've commented out both the /home_nfs and the /xfn entry, but without
success - same behaviour, the daemon starts, and fails a few seconds later
with the above message.
When I reboot the machines, the automountd comes up and runs - until 4 o'
clock...
(There are some cronjobs, e.g. a quota-checker running at 4 o' clock - but I
can't imagine that this is the problem...)
Any ideas?? Hope someone can help us, since it's a real severe problem which
blocks our complete network...
Thanks, and have a nice hackin',
Harald
