rsync - Mar 2004 - FW: error writing 4 unbuffered bytes - exiting: Broken pipe

I have a filesystem from a different machine nfs mounted on the 
machine that is running rsync.

rsync  version 2.5.5  protocol version 26
Copyright (C) 1996-2002 by Andrew Tridgell and others

              IPv6, 64-bit system inums, 64-bit internal inums

I am trying to create a backup image on the remote machine, but thanks to NFS it
looks like a local filesystem.

The command I am using is 
 rsync -rluRtpPv --delete /net/moe/bne/* /net/burns/bne_old/ | tee rsync_report2

I then get this:

rsync: error writing 4 unbuffered bytes - exiting: Broken pipe
rsync error: error in rsync protocol data stream (code 12) at io.c(463)
rsync: error writing 69 unbuffered bytes - exiting: Broken pipe
rsync error: error in rsync protocol data stream (code 12) at io.c(463)

I searched the gmane group for a solution to no great satisfaction.

There is lots of space on both drives.  When I rerun rsync it picks up where it
left off and works for a while.

Any help would be appreciated
