Description of problem:

Had a 2node cluster with 2 volumes 2*2 dist-rep 'ozone' and 4*1 distribute
'nash',  with glusterfind sessions for both of them. Glutserfind command on
ozone resulted in a crash (bug 1228017), post which I carried on my testing
with nash volume.

Did creates, renames, file moves, metadata changes and operations of those kind
at teh fuse mountpoint of nash. Ran glusterfind commands pre and post everytime
there was a change. Left the setup untouched for close to 3 hours. 

Ran the glusterfind pre command again, without doing any changes on the
mountpoint, and it resulted in an error on node2, stating 'Historical
changelogs not available'. It managed to get the changelogs on node1.
glutserfind list displayed healthy session entries on node1 but 'session
corrupted' entries on node2. 

Brick logs displayed the following error on node2:
