Subject Re: 5.3 question and server upgrade question...
Date Tue, 05 Nov 2013 15:28:28 GMT
Thanks for the response...

Any idea on the round-robin not working? I have a queue with 16 consumers,
all have pre-fetch set to 1. Five consumers are actively processing
requests and 3 requests are pending.... the 11 other consumers are idle.
History has shown that a new request may go to one of the 11 idle works,
but its like those 3 requests are reserved for some of the working ones. I
can't figure out what setting would help this, or if this just was a bug
with 5.3....
