Last I checked soumya and Niels are working on a similar bug. Assigning it to Niels for now.

As of glusterfs-6.x have not heard of this issue. Considering we haven't run a test to validate this, marking it as DEFERRED for now, and revisiting this after couple of releases.

If you find the issue is happening still with glusterfs-6.x releases, feel free to re-open it.
