Aaron,

Thanks for the logs, this was really helpful.
Looks like there is a handover race in the OSM -
SM on node A misses the fact that SM on node B
have gave up its mastership.

There is a bugzilla issue the describes all the
details of this race:

https://bugs.openfabrics.org/show_bug.cgi?id=1499

I've updated the issue form with your case, and 
we will continue following this bug there.
