transport won't shutdown, stuck in countdownlatch
-------------------------------------------------
Key: AMQ-1252
URL: https://issues.apache.org/activemq/browse/AMQ-1252
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 4.1.1
Reporter: Alex Burgel
i have a network of brokers setup. when i shutdown the brokers, one of them
always gets stuck waiting. i've pasted the relevant part of a thread dump
below. you can see that the tcp transport is stuck waiting for the connection
to host 10.4.7.108 to start up. the problem is that this host has already been
shutdown. so the other host will be stuck waiting forever.
this post seems to be relevant to the issue:
