Yu Jian,
it looks like this is potentially a race in the test case? We don't run mmp.sh test_5 very often - only in "failover" mode. I was working on http://review.whamcloud.com/3715 to try and get these tests to run in more cases, but I haven't completed it. In theory, we should be able to run the MMP tests all the time, since the VM nodes are all on the same hosts.

We're reducing this from a blocker, since I think the problem is in the test case and not in the code. Please change it back if you disagree.
