I have the same problem, since migration to 2.0.
Mainly it happens on INBOX (well, I’ve only seen this happen on INBOX), but I did not found a way to reproduce it.
It happened to the same user more than once.
I have 15 users.
Only one mailbox a time, well, as I said before it happens only on INBOX and yes, more than one user per time.

I have no load balance, no director.
