Subject Re: Could not correlate acknowledgment since update
Date Tue, 28 Jun 2011 09:56:52 GMT
ackType=0 is a delivered ack which is used to increase the prefetch
within a transaction or with individual ack but it is not critical.

The error indicates that the broker does not have knowledge of the
dispatch of that message to the consumer, as a result it has no
message to ack. This can occur after failover if there are pending
acks that get replayed.
