We have suddenly run into a problem with our server running out of heap space. When I look at the hprof file generated, I see alot of activemq data hanging around. Is this normal? It almost looks like the messages are not getting garbage collected after sent. This worked fine in the past. We have not change anything recently except for deploying some new application code. Any ideas what could cause this?
