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

This issue relates to the following test suite run: http://maloo.whamcloud.com/test_sets/71605d20-82b2-11e3-b715-52540035b04c.

The sub-test test_45 failed with the following error:

test failed to respond and timed out

Client console shows:

Not sure if this is a dup of LU-2746 and after this error, both the client and OST reboot.
