Niu, just as a general guideline, it is good to have more descriptive bug reports, so that when Oleg and I are looking at this bug/patch for landing, that it is possible to get some understanding of the problem being hit.

This bug report does not indicate whether this is an issue you found during inspection, hit during testing, how severe the problem is (deadlock, error to application, oops, node hang, data corruption, etc), or how frequently or under which conditions it is expected to be hit.

Andreas, thanks. I'll put more information when reporting bug next time.
