Hi everyone! I've been using ActiveMQ for some time, but have run into several issues lately which I haven't been able to figure out what is causing them. I use the NMS Client Library from C# using version 5.3.0 of ActiveMQ, but have also tried using version 5.3.2. I am also using the latest versions of the NMS client libraries (Apache.NMS.ActiveMQ.dll + Apache.NMS.dll). I'm using persistent queues, without producer flow control disabled. The prefetch is set to 1 and auto acknowledge.
The first problem is that from a producer, the send method can sometimes block indefinitely. Similar, when trying to stop the program, it blocks when trying to close the connection. Sometimes I also get this error "Apache.NMS.ActiveMQ.IOException: Channel was inactive for too long: tcp:// 127.0.0.1:61616/?nms.PrefetchPolicy.queuePrefetch=1&wireFormat.MaxInactivityDuration=0 ". I saw on the mailing list that setting the "wireFormat.MaxInactivityDuration=0" would deal with this situation, but it didn't remedy this situation. The connection and the session objects are used for a long time. Is there any guidance for how long a connection and session should be used? I also tried using the failover which just one address, like this: "failover:(tcp:// 127.0.0.1:61616?nms.PrefetchPolicy.queuePrefetch=1&wireFormat.MaxInactivityDuration=0)", but then it gave me some other issues, the number of threads started to spin up. Can the same connection and session be used over several threads? Anything that could shed some light on these issues would be very welcome. Thanks, Frank
