This failed about 11x per week for the past 4 weeks.

I suspect the test timeout is because the cleanup_src_tgt step is taking a long time to do rm -rf $DIR/$tdir after running dbench, though that doesn't absolve the original error. At least there aren't any Lustre errors in the console logs for any of the nodes.

The recent failures have a lot of the following errors, though I'm not sure if these are new or not:

I think this is another:
https://testing.hpdd.intel.com/test_sets/3efa00dc-6fdf-11e4-85fc-5254006e85c2

It reports as a TIMEOUT, not a FAIL, but the test log says:

Only in /mnt/lustre/d2b.lustre-rsync-test/clients/client1/~dmtmp/PARADOX: __QB4.MB
lustre-rsync-test test_2b: @@@@@@ FAIL: Failure in replication; differences found.
