Subject Cascading SlowConsumer Advisories
Date Thu, 14 Jun 2012 22:13:10 GMT
I recently experienced an activemq failure where the service became
unresponsive. A thread dump showed a large number of threads whose names
indicated they were related to ActiveMQ.Advisory.SlowConsumer.Topic.xxx But
the weird thing is that the topic that was being alerted on was another slow
consumer advisory topic! This was repeated over and over with deeper and
deeper nesting. An example:

"Topic
ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Advisory.SlowConsumer.Topic.ActiveMQ.Adviso
.....

This is an indication to me that ActiveMQ is recursively creating
SlowConsumer advisory topics on it own advisory topics.

My only solution was to restart the process.

Does anyone have any idea what was going on? This has happened occasionally
before and I would really like to know what is happening.
