Subject Re: Broker to Broker prefetch problems
Date Fri, 28 Jun 2013 13:20:48 GMT
not sure if the prefetch matches those of the networkConnectors, seems
to be 1000(default) vs 15000 so it may be a connection
temp advisory consumer. Can be disabled with connection url param
watchTopicAdvisories=false

If you can find the consumer
ID:mco-broker8-57609-1372346502469-88:1:1:1 via jmx. ensure it has
asyncDispatch=true,
otherwise a blocked connection/consumer can block dispatch to others.
Also. it has 147 destinations, which is a lot. that may help identify it.
Are all of the clients using the same version, there was a fix for an
issue with non asyncDispatch consumers that may be relevant if not:
