Subject Re: JMX shows -16 for queue size? Shows 16k before a restart...
Date Sun, 23 Nov 2014 23:07:26 GMT
ha.. I actually spoke too soon.  We have 3 queues with negative queue
sizes.
There are some bugs WRT this…

https://issues.apache.org/jira/browse/AMQ-4598

… but it looks like this issue was fixed.

It’s odd that my AMQ server was at a LARGE number of messages, then on a
restart, it’s in a negative count.

VERY weird.

Any advice?
