-----------------------------------

Wouter, thanks for testing the fix. I've sent a pull request to merge these changes upstream.

As for the WARN messages you mention, under heavy load, if this turns out to be an issue in the AS7 code, feel free to either open a forum thread or a JIRA with the details.

> When running distributed transaction over multiple clusters, memory is depleted in a matter of minutes. 
> We are using EJB's without transaction annotations (default behavior) and  remoting as described in 
> https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+server+instance.
> Heap dumps are available at http://people.cs.kuleuven.be/~bart.vanbrabant/jboss_dump/.
> The IBM heap analyzer blames org/jboss/as/ejb3/remote/EJBRemoteTransactionsRepository as the root cause, taking up 95.73% of memory, through the transaction map.
> If more info is required, I can provided our test application.
> Thanks,
> Wouter
