Subject Re: A Question About Message Groups
Date Wed, 06 Dec 2006 14:57:56 GMT

Hi,

Another question has cropped up, if, lets say, the consumer were to go down
whilst processing a message, does the message it was processing go to the
back of the queue, or remain as the fist to get handed out to the next
consumer that is available?  (the consumers are using auto acknowledge),

Thanks,
Osh
