The more I dig into this....the more I suspect kernel related. Basically an open() is done to an NFS mounted file with O_SYNC, followed by a write(). On the RHEL machine, the NFS write is done correctly...with a FILE_SYNC sent to the server, on the Ubuntu client, the NFS write is sent UNSTABLE, i.e. it doesn't wait to receive notification from the server that the data was sync'd.
