SubjectRe: [NFS] Spurious NFS ESTALE errors w/NFSv3 server, non-v3 client

Not that large, no. They're on the order of tens of
megabytes, maybe 150 MBytes max.

See below for the end of the tcpdump log, which concludes with
the ESTALE. I've got the entire log saved, which is about 1.4
MB gzipped, available as http://bklyn.org/~cae/tcpdump.log.gz

For this test, server was linux 2.4.9 w/nfsv3 enabled, client
was 2.4.7 with no nfsv3. Filesystem mounted on the client as:

tela:/shn on /shn/tela type nfs (rw,rsize=8192,wsize=8192,soft,addr=192.168.1.2,addr=192.168.1.2)

Let me know if I can provide any add'l info that might help.
