Not able to reproduce with the latest build 51. Yesterday's BVT also didn't reproduce this. Still I want to try some more attempts , before coming to conclusion.

Comment 9 Vivek Agarwal 2013-12-20 05:47:28 UTC
Have not seen this in the past couple of bvt runs.

Comment 10 Lalatendu Mohanty 2013-12-26 06:44:58 UTC
The smbd crash issue came during last two BVT runs. We are not able to recreate the issue manually, However Automation is hitting it intermittently. Hence reopening the bug.

Comment 11 Lalatendu Mohanty 2013-12-26 06:58:49 UTC
The latest crash came in below BVT build 

BVT Build version: glusterfs-server-
