Hello,

In your Camel route you seem to route message from various destinations =
on the broker to other destinations on the same broker.
Is it possible that the destinations you route message to are getting =
filled up (not all, but some of them).=20
If that happens, producer flow control might kick in, causing the Camel =
route producers to be put on hold until more messages get consumed.=20
If the Camel route producer is stalled, the entire Camel route is =
stalled.
http://activemq.apache.org/producer-flow-control.html

I suggest you monitor all queues and topics on the broker using either =
the web console or JMX.=20
Also, a thread dump of the broker and the Camel route (in case it runs =
external to the broker) could help you to find out in what state the =
broker and your Camel route are.=20
