Description

This issue was created by maloo for sarah <[e-mail]>

This issue relates to the following test suite run: https://maloo.whamcloud.com/test_sets/91d8ae78-755b-11e2-bf59-52540035b04c.

The sub-test test_bonnie failed with the following error:

test failed to respond and timed out

From the stdout log, I found the test ran extremely slow compare to the success run:

It took almost 45 minutes for the failed test:

Only 9 minutes for the success test:
