Update:
The autoReconnect change didn't fix it
(but I will remove it from the jdbc url anyway)
I just downgraded to 1.4.2_09 and restarted... now I don't have much
mails anymore, but we'll see if it happens later.
It happened again. Everyone is waiting for this thread to unlock the

Note that RemoteDeliveryVoid is almost equals to RemoteDelivery (from
current 2.3) and JDBCSpoolRepository is the one from the current 2.3.
Requesting the dump 10 minutes later I still see the same identical dump
with that thread runnable and with the same stack.
Looking at musql I see that the pending messages query last 2-7 seconds
and is repeated in a infinite (or very long) loop.
I don't understand why it does not exit from this loop, I'm investigating..
