Subject [jira] Commented: (AMQ-2901) Repeating error of client on reconnect
Date Mon, 25 Oct 2010 09:44:41 GMT


Dirk Alexander Schäfer commented on AMQ-2901:

the following looks interessting to me, too. we've got a durable topic cosnumer configured
in our muleInstanze. once the broker dies the durable topic consumer is connected to, the
consumer tries to reconnect and gets forwarded to the second broker by the load balancer.
the second broker than refuses the connection because it thinks that there is allready a client
using the specific durable topic consumer id.

>          Components: Broker, JMS client
>    Affects Versions: 5.4.0

> recently we upgraded our activeMq instanzes from 5.3.1 to 5.4.0. we also upgraded the
client API used in our mule-based services. since that upgrade we are facing with strange
reconnet errors. we have a network of brokers with two instances. they are located behinde
a hardware loadbalancer over which our clients connect to the brokers. if we restart one of
the brokers, the clients connected to it perform a reconnect and are getting linked to the
other broker. in our services we use a lot of queues and topics.
> it seems that some topics are unable to reconnect randomly. on one of our client machines
the reconnect to a durable topic wasn't possible anymore (Root Exception was: Durable consumer
is in use for client: myUniqueConnectorName and subscriptionName: myDurableSubscriberName(JMS
Code: null). Type: class javax.jms.JMSException ). on the other machine a reconnect to another,
non-durable topic (Root Exception was: Channel was inactive for too long: /w.x.y.z:61616.
Type: class org.apache.activemq.transport.InactivityIOException ). they did not reconnect
at all until the services were restarted.
> we were not having this problems with the version 5.3.1.
