--- Comment #6 from Niels de Vos <ndevos at redhat.com> ---
Could you please provide the following details, preferably on an environment
that does not have anything else to do (a one-server Gluster env works fine for

0. create a one-brick volume for testing
1. enable more verbose logging for the NFS-server
    # gluster volume set $VOLUME diagnostics.client-log-level DEBUG
2. start a tcpdump to capture the NFS and GlusterFS traffic on the Gluster/NFS
    # tcpdump -s 0 -i any -w /path/to/tcpdump.pcap tcp and not port 22
3. do whatever XEN-Server things are needed to make it fail
4. kill the tcpdump (CTRL+C or just 'pkill tcpdump')
5. gzip the /path/to/tcpdump.pcap
6. disable the logging
    # gluster volume reset $VOLUME diagnostics.client-log-level

Attach the /var/log/glusterfs/nfs.log and the gzipped .pcap file to this bg

It might be very helpful if you can also do this test with 3.6.1 where it
should work. We can then compare the tcpdumps and check where things start to
go wrong.
