We set up our active MQ to fail over (failover://(host1:61616,host2:61616)).
I'm getting these fairly frequently, and I've only seen them related to memory in other people's posts. Unlikely to be this case as I'm operating in a low volume test environment. Any leads as to what else might be the problem?
