Description

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

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/02b93f90-cdaf-11e6-9f17-5254006e85c2.

The sub-test test_311 failed with the following error:

objs not destroyed after unlink

This looks a lot like LU-8523, but that is closed as Fixed.
Raising this new ticket for a fresh instance on master.
Somebody more expert needs to figure out if this really is a new bug or the old bug coming back.

 sanity test_311: @@@@@@ FAIL: objs not destroyed after unlink 

It looks like the check is still too strict even with the fix from LU-8523, I'll make a patch later.
