Vladimir Blagojevic commented on JGRP-788:
------------------------------------------

I've tested attached SharedTransportConcurrenyTest and shared-transport.xml on a cluster of 8 machines for over 30 runs. Never seen a problem of a lockup or a test failue. Consider closing this issue.

> Further to the testing in ChannelConcurrencyTest, we are now verifying 2.6.3-CR2 with the new shared transport enabled.
> It appears to be a lot slower than the equivalent number of channels without shared transport, the CCT timeout of 2 minutes often being insufficient.
> Will attach config and test cases.
> I've not been able to catch it actually wedged yet, but will post as soon as I get a confirmed sighting.
