Major Description
Hi,
Broker version : 5.10.0
Problem :
I am using ActiveMQv5.10.0 broker in my setup. In my broker I am facing a weird problem where a durable subscriber is not able to connect to the broker because of stale subscription shown by the broker with the same client id. Please note that this issue is not reproducible, I tried but not able to reproduce. It happens sometimes.
Details:
In my application I am creating 3 durable subscriptions on different topics. I am using PooledConnectionFactory with maxConnection=3 to create connections for each listener. I am using separate Spring Default message listener container for creation of the each listener.
Sometime when I start my client, I get below exception :
-----------
listener.DefaultMessageListenerContainer.refreshConnectionUntilSuccessful():907 ERROR]: Could not refresh JMS Connection for destination 'topic://test.newPnlSpn' - retrying in 5000 ms. Cause: Broker: mqbrokerdev - Client: new_pnl_spn_test_client already connected from tcp://a.b.c.d:2338
-----------
But when I check connections from "a.b.c.d". I don;t see any connections from the IP. Even on JConsole, it does not show any clients connecting to the same topic with this client_id.
In some cases i observed that this is the IP address where my client was previously running.
Because of this issue my current client which is running from some other IP address is not able to connect to the broker.
I suspect that there is some race condition in ActiveMQ connection pooling. This is a serious issue I am facing in my setup, My clients are not able to connect to the broker.
When I face this issue :
I tried to restart the broker by clearing out the persistent store, but this issue was still there. It only got resolved when I changed the client ID of my listener.
Which means broker somewhere keeping stale connection state for this client id. As soon as new client id comes, it start working properly and connecting to the broker.
