Subject Re: Even after upgrade to ActiveMQ 5.4.0, still seeing negative #'s in the "Pending Msgs" column
Date Wed, 08 Sep 2010 20:42:54 GMT
Gary,
* *
*Sorry - last message was incomplete - technical difficulties*

Haven't had any luck reproducing this issue with a JMeter test, however, I
can reproduce
it on a fairly regular basis using our in-house application script, which
puts tons of application
messages on the queues.

Also, I don't seem to see this issue when there is only a single broker
running, only when
there is two or more running in a network of brokers configuration.

When I do see this issue, I •do• see it on JConsole as well as in the
ActiveMQ WebAdmin console.

*Possible Test Case:*

To reproduce, start up multiple Producers, both of which are throwing
80,000+ messages
to the two brokers (which are configured as a network of brokers ) and have
two consumers running on
separate servers pulling items off of the application queue(s).
