Description (partial)

Error on PUB-SUB setup:Mdns UDP socket failed. Stopping the MDNS thread.

Symptom:
This occurs when the jabberd is unable to send on the MDNS socket; there's nothing to indicate what the cause of the error was, but the end result is that the thread responsible for MDNS shuts down and isn't restarted. I suspect that this prevented imp2 from re-establishing the connection to imp1 later on after the HA failback.

Conditions:
PUB (imp1) and SUB(imp2) IM&Presence nodes: 10.0.1.10000-3.
They are both in the same subnet, so default MDNS setting was used.
