Duplicate — Fri, 30 Oct 2015 00:34:16 +0000

This issue was created by maloo for Bob Glossman <bob.glossman@intel.com>

This issue relates to the following test suite run: https://maloo.whamcloud.com/test_sets/cfaf9a1a-9de0-11e2-8513-52540035b04c.

The sub-test test_5 failed with the following error:

test failed to respond and timed out

This failure is happening a lot lately:

Failure Rate: 54.76% of last 42 executions [all branches]

The mds panics and crashes during a mount command in test_5. This is with fail_loc set to 0x1504. From the mds console log:
