> Stale connection hanging at broker during consumer crash
> --------------------------------------------------------
>
> Key: AMQ-7059
> URL: https://issues.apache.org/jira/browse/AMQ-7059
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, Command Line Tools, JMS client, OSGi/Karaf
> Affects Versions: 5.14.0
> Reporter: Hemanathan
> Assignee: Jean-Baptiste Onofré
> Priority: Major
>
> Stale connection hanging at broker during consumer crash :
> Step1 :
> When a consumer is getting attached with ActiveMQ broker, the consumer count
> is getting increased with one , which is verified through "dstat" command .
> Also the "netstat" from client machine shows one connection establishment
> with broker.
> Netstat:
> tcp 0 0 x.x.x.x:61617 x.x.x.x:44332
> ESTABLISHED 18625/java
> dstat value is:
> Name Queue Size
> Producer # Consumer # Enqueue # Dequeue # Forward # Memory %
> consumer.xyz.virtualTopic.abc.productUpdateNotificationEvent.1_0 8
> 0 1 10 2 0 0
> Step2 :
> Kill the client connection and no such connection in netstat from client
> machine. But still the connection hanging with broker and dstat showing the
> same result as before.
> Netstat:
> -NA-
> dstat value is:
> Name Queue
> Size Producer # Consumer # Enqueue # Dequeue # Forward # Memory %
> consumer.xyz.virtualTopic.abc.productUpdateNotificationEvent.1_0 8
> 0 1 10 2 0 0
> Step 3:
> Few of the message (multiples of 1000) not getting de-queue even after the
> new client getting connected. So the number of messages and number of
> consumers is getting increased on every attempt of client termination. When
> we try to change the "prefetchPolicy.queuePrefetch" property on consumer
> side, its reflecting so the number of messages are hanging (as configured in
> property . Eg. If we set value as "prefetchPolicy.queuePrefetch=10", then 10
> messages are hanging on the queue)
> Step 4 :
> After re-starting the broker , all the pending messages are getting
> de-queued, Where one client is up and running .
