[rabbitmq-discuss] System.OutOfMemoryException

[Phil Marino]

Hi - we're running RabbitMQ 3.1.3 on Windows Server 2008 R2, using the .Net 
Rabbit client library.
 
We're troubleshooting a distributed transaction problem involving Oracle.  
But when this problem happens, we also see thes from Rabbit:

I will say that the server appears to have plenty of RAM available.
I'm sure that I don't have enough information to identify what's happening, 
so one question I have is: what else do I need?
 
It looks like we're trying to enlist in an aborted transaction, but I'm not 
sure why the Out Of Memory exception is thrown.  Any suggestions?
 
 
Thanks,
Phil
