Sounds like a very interesting problem. The only time I've gotten such
errors have been NFSv4 issues between Linux and Solaris hosts, never
with a NetApp.
You might try asking on the linux-nfs[1] list as well as the
toasters[2] list. I'd be interested to hera what you come up with.
Very strange symptoms though. Are you using NFS over TCP or UDP? It
seems like one side is attempting to use a stale session...
I've always found NFS stuff like this very difficult to troubleshoot.
If you can reproduce the problem on demand maybe you could get a packet
dump right when the issue begins...
