We've had reports of users hitting this in 3.8

eg:
https://bugzilla.redhat.com/show_bug.cgi?id=947985
https://bugzilla.redhat.com/show_bug.cgi?id=956730 

I'm sure there are other reports of it too.

Would be good if we can figure out what fixed it (if it is actually fixed)
for backporting to stable
