Hi Trond and others
I would like to report an NFS oops on one of our machines, possibly
involving lockd. It is a stock Redhat 7.3 installation running 2.4.18-2 out
of the box. The machine is exporting user home directories for between 50
to 100 unix clients. The clients are a mix of Digital unix boxes (v4.0d or
later) and various Linux versions (Redhat 6.1/7.1/7.2/7.3, Slackware 8.0).
Initially things work fine, but after some time (or perhaps after a certain
number of connections and/or NFS operations) the following oops occurs:

A few weeks ago there was a similar report on linux-kernel which used xfs as
the filesystem. We are not using xfs - just ext2.
The oops appears to crash lockd (it doesn't appear in the process table
after the oops has occured) and all nfsd processes are locked in the D state
indefinitely. The machine needs to be rebooted to restore operation. It
goes without saying that in this state, all clients hang up until the server
has been rebooted.
If you have any further questions I'm happy to attempt to answer them. This
was going to be our new production server, but until this problem is
rectified we're going to have to fall back to our original DEC - we can't
afford to have 100 people unable to work for days on end.
Please CC me any replies since I do not subscribe to either list (nfs or
linux-kernel).
Best regards
jonathan
