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.

This is related to, but looks different than, LU-4781. This bug just reports a replication difference, while LU-4781 reports errors during replication.
