We had a hardware failure on Monday 2/2, rebuilt the server on another system.
We used the same disk and raid controlers on the replacement server so no reinstalls were done.
Tuesday 2/3 every thing appears to be working ok.
Wednesday I come in and check and the Deferred Que is at 1000+ messages.
A check of Zimbra.log shows a large number of these messages
did a zmfixperms with no effect.
