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

Hi,

The fix seems to work.

Under moderate load, the servers seem to hold out well, garbage collection time are stable. 
Under heavy load, the servers get stuck, but this is probably due to unrelated causes. We will investigated further this week. 

However, periodically, the tier that initializes the transactions prints out a massive number of log messages of the form:

17:49:06,308 WARN  [com.arjuna.ats.jta] (Periodic Recovery) ARJUNA016037: Could not find new XAResource to use for recovering non-serializable XAResource XAResourceRecord < resource:null, txid:< formatId=131077, gtrid_length=29, bqual_length=36, tx_uid=0:ffffc0a87a0e:-22a62bdc:4fe021f9:936f, node_name=1, branch_uid=0:ffffc0a87a0e:-22a62bdc:4fe021f9:9370, subordinatenodename=null, eis_name=unknown eis name >, heuristic: TwoPhaseOutcome.FINISH_OK com.arjuna.ats.internal.jta.resources.arjunacore.XAResourceRecord at 7b9428f7 >

>    Affects Versions: 7.1.1.Final, 7.1.2.Final (EAP)

> 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
