Weird NFS behaviour...

We have 2 AS1200 running ASE 1.5 & DU 4.0E. These have been running fine
until yesterday afternoon when one node stopped serving NFS.

On inspection the mountd & nfsd processes had gone uninteruptable sleep.

The node was only on pk1 so I loaded pk4. This had the effect of screwing
the operating system good and proper (cannot build kernel) so I reloaded
the OS.

The 2 NFS services that are supported by this ASE are running fine on the
other node (slowly 'cos it's doing twice as much work).

After reloading the OS, installing ASE & patching the OS with pk4 I
re-add the node to the ASE. One of the NFS services fails over & the NFS
daemons go uninterruptable sleep.

This smells now like a hardware problem - but what hardware fault could
cause this behaviour? There is nothing logged in the binary errorlog
(checked with decevent v3) or in any of the messages files. Running the
ASE logger in debug mode yields no useful output.

Any help appreciated!

Regards,

Jonathan
