Dear Tim, In the meantime, I found the cause for the problem which was introduced to the client in version 5.14.1 with the following commit:
https://git-wip-us.apache.org/repos/asf?p=activemq.git;h=06e929f There, a default socket timesout of 30 seconds was added which conflicts with the time it takes to make a keep alive request over http. I was able to resolve the problem by patching the class to increase the timeout to 90 seconds. The problem is unrelated to the broker and only affects the client. I also updated my ticket descriotion accordingly. Cheers Samuel -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
