Messages not delivered to connecter consumer
--------------------------------------------
Key: AMQ-3697
URL: https://issues.apache.org/jira/browse/AMQ-3697
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.5.1
Environment: SunOS 5.10 Generic_142909-17 sun4v sparc SUNW,T5140
Reporter: William
Priority: Critical
I am using ActiveMQ 5.5.1 and sometimes messages are not dispatched to
connected consumers.
A single broker is used. No transaction and no persistence is used for message
delivery. Message consumers are spring template made for topic consuption.
Optimize acknowledge is enabled and acknowledgment is auto.
By Looking at JMX Topic MBean I can see that messages are received but not
dispatched (and of course non depueued). I noticed that disptatched count was
100 more than dequeue count.
>From JMX :
* Received count : 4502
* Dispatched count : 3756
* Dequeued count : 3656
If a start a new consumer on the same topic, the messages are only dispatched
to the new consumer while the older one is still seen as connected (consumer
count on the mbean is 2). Once the problem appear the only solution is to
restart the consumer or the activemq instance.
It seems that even if the consumer is seen as connected, messages as not
dispatched for an unknow reason.
Which logs can I enable in order to diagnose the problem (on activemq side
and/or consumer side) ? I have already made a thread dump, not thread are blocke
