[jira] Commented: (AMQ-2749) Broker hangs in TopicSubscription.add
[ https://issues.apache.org/activemq/browse/AMQ-2749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=59542#action_59542 ]
Dennis Klinkott commented on AMQ-2749:
--------------------------------------
Now we got the same problem on a preprod machine.
This time it is not a stomp connection that causes the freeze.
This is the thread that holds the lock that blocks all other threads:

I wonder how TopicSubscription.add can freeze?

> Our broker suddenly hang in production environment. We created a bunch of jstacks to see what the reason is.
> The jstacks show that the broker waits with many threads in doMessageSend:

> So it is the client 10.231.233.117 that has a stomp-connection to the broker, causes a TopicSubscription.add and causes the broker freeze.
> This is how we configure our openwire transport-connector in the activemq.xml:
> <transportConnectors>
> <transportConnector name="openwire" uri="tcp://0.0.0.0:61616"/>
> <transportConnector name="stomp" uri="stomp://0.0.0.0:61613"/>
> </transportConnectors>
> We took jstack-dumps with a distance of 9 minutes. Both are attached. In both dumps it is the same TopicSubscription.add that causes the hang.
> How can we solve this issue? Looks like the connection should run into an timeout but doesn't. Is this an activemq bug? Can we somehow set the broker openwire timeout parameters?
> Thanks for any hints.
