Subject Re: [jira] Reopened: (AMQ-1214) threads not stopping causing memory leaks which can lead to OutOfMemoryError
Date Tue, 24 Jul 2007 03:57:20 GMT

We used jhat and found out that there are over 1.6 million instances of the
org.apache.activemq.filter.DestinationMapNode after just deploying one
service in ServiceMix.

The second largest number of instances is 3001.
