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.
Have not seen this in the past couple of bvt runs.
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.
The latest crash came in below BVT build BVT Build version: glusterfs-server-3.4.0.52rhs-1387920125.el6.x86_64.rpm
Can I please get the link of the patch which fixes this bug?
Code posted at: https://code.engineering.redhat.com/gerrit/#/c/17893/
I am not seeing this issue with recent BVT runs. Hence marking this as verified.
