The web console responds fine, the Stomp connector throws the exception. The
AMQ config shows -Xms512M -Xmx512M
-Dorg.apache.activemq.UseDedicatedTaskRunner=true

This system has been running without incident for several months. Two weeks
ago I changed the config to enable  gcInactiveDestinations="true" on queues.
Since then we've had two Stomp "crashes" inside one week.

Does this GC process require much more RAM or something? Or am I likely
looking at a bug?

Thanks,

James
