--- Comment #2 from Soumya Koduri <skoduri at redhat.com> ---
I see nfs-ganesha re-exporting the volume -

02/08/2016 06:28:15 : epoch 57a071e6 : gqas014.sbu.lab.eng.bos.redhat.com :
ganesha.nfsd-19047[dbus_heartbeat] mdcache_lru_clean :INODE LRU :CRIT :Error
closing file in cleanup: Operation not supported

ganesha.nfsd-19047[dbus_heartbeat] glusterfs_create_export :FSAL :EVENT :Volume
testvol exported at : '/'

Aug  2 06:28:57 gqas014 systemd: Unit nfs-ganesha.service entered failed state.
Aug  2 06:28:57 gqas014 systemd: nfs-ganesha.service failed.

And around the same time crash happened. So somehow volume is being re-exported
resulting in crash which is being addressed as part of bug1361520 . Jiffin is
building RPMs with the fix applied. Please re-test post that.
