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 list as well as the
toasters 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...
