Subject Re: Messages not delivered after failover.
Date Tue, 15 May 2012 20:57:28 GMT
the client sees the disconnect due to the firewall, but does the
broker see the same disconnect? you may need to configure keep alive
on the broker transport connector to ensure that it sees the client
You can check via jmx (jconsole), to verify that the consumer goes
away. If it remains, then prefetched messages will still be inflight
and not visible to other consumers till the connection is closed.
The inflight count on the destination will also give an indication if
this is the case.

But it seems to me that once the connection is restored, the client should be able to receive
messages again, but does not.

As mentioned previously, the client consumer program is in use on several servers, where it's
working fine - just this server is being persnickety.

Apparently the connection is failing and then once reconnected due to failover being set up,
it no longer gets messages sent to it. The only thing I changed in the log was to anonymize
our IP address. The client program is using activemq 5.5.1 jars, and is talking to an ActiveMQ
5.3.1 broker (slated to be updated to 5.6.0 on the 19th).
