> Hey guys,
> We're noticing a pretty strange issue processing a large number of JMS
> messages. After about 20k messages, messages consumed per second drops off
> and there's heavy GC activity (smells like a memory leak). What interesting
> though is the server continues to run and doesn't OutOfMemoryError. A simple
> restart of TomEE (but not the broker) temporarily fixes the problem. We're
> using an external broker, not the internal one
> What's interesting, is that Jonathan Gallimore and I were talking about a
> similar issue with Websockets. We noticed that eventually the servers will
> exhibit the same behavior once enough websockets are opened and closed. This
> issue occurs infrequently enough because we might handle 20,000 websockets
> over the course of a few days, but we can process 20,000 JMS messages in a
> few mins.
> I have a heap dump from the issue and several jstacks. I'll be honest, I'm
> not sure where to start. In the past I've solved memory leaks by careful
> code audits. Our codebase happens to be mostly stateless, with everything
> else being managed by CDI scopes (ApplicationScoped and TransactionScoped).
> What's a good way to get started?
