Attached is the sequence of the tcpdump exported as a text file. This is a freebsd 7.0 client talking to the above mentioned FreeBSD 8.0 NFS server. I've seen similar behavior from my FreeBSD 6.1 NFS clients too.
This will just loop like this forever. At some point after a day or so the FreeBSD 8.0 server will then lose all networking (still can access the console just fine). Rebooting fixes everything for a day or so until a client has problems again.
I've tried different network driver igb->em, UDP->TCP for NFS, enabling NFS locking on the server/clients (lockd, statd).
I'm out of ideas so hoping this tcpdump sheds light on how it's getting stuck in this loop.
Thanks,
Alan
