2019-10-22 Thread Peter Hicks

Durable subscription not receiving messages

2015-02-28 Thread Peter Hicks
Hello I'm using ActiveMQ 5.10.1 running under OpenJDK 1.13.6. I'm encountering a problem where I reconnect to a topic using a subscriptionName, but no messages are dequeued. Looking at the conversation in Wireshark: * Client sends a CONNECT frame with a client-id * Server sends a
