Hi Jerry,
Thanks for the reply. I'll check this if it reoccurs again.
We've turned off strict locking to see if this helps. This was on a hunch
that it was a lock issue.
To answer your question, the access to the main share on this server is
via the automounter to a local directory. For example the automount map
/hwnet/ccvobs mounts /export/vobs on this server. The share [vobs] is
mapped to /hwnet/vobs. The default timeout is 60 seconds and we do see the
automounter expire and remount this mount point frequently. While we're
not re-exporting this file system there are certainly times when the
automounter will apparently unmount and remount it.
Note: that during the "event" the filesystem is available both locally and
via the automounter.
-John

Are you reexporting NFS shares by chance?

A good theory (which would be true if re-exporting NFS
shares and the NFS server got stuck).

look in /proc/<pid/fd and see what file fd 13 is.
cheers, jerry
