Sure have. Here is what I found.
One of m brokers (on another machine) was hitting it's store usage limit so it stopped allow producers to send it messages. The two other brokers then had their queues getting backed up because they could not route from their queues to to this one. I fixed the usage limit configuration and it allow new messages to flow, but the old ones were still stuck, even though I have retries configured to run for a few days. I had to actually restart all of them to get them to empty out. A very painful experience. Not sure if this an ActiveMQ or a Camel issue because it basically stopped routing the messages and we use Camel for that.

I check the MBeans and it says they are inflight, so the consumer hasn't picked them. In my case, the consumer is a POJO method in the same JVM. Also, it appears retries are not happening. It just gets stuck. Before I attach my configuration, etc. I am wondering if anyone has seen this or has idea of what might be happening? Thanks. Jason
