*****************************************
Code Location of the Issue and Fix
*****************************************
This issue has got something to do with
org.apache.activemq.ActiveMQConnection.java not checking if the connection is
started or not before creating JMSSession is created.
Method:
public Session createSession(boolean transacted, int acknowledgeMode) throws
JMSException {
//Fix is to check if connection is started or not before creating a session :
synchronized(this.startMutex){
if(!this.isStarted()) {
start();
}
}
checkClosedOrFailed();
ensureConnectionInfoSent();
LOG.trace("Connection started : " + isStarted() + "Connection Hash Code
: "+ this.hashCode() +"Connection Details: " + this );
// rest of the code
// goes here
}

> Key: AMQ-3460
> URL: https://issues.apache.org/jira/browse/AMQ-3460
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.3.1
> Environment: java version "1.5.0_15"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
> Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_15-b04, mixed mode)
> Reporter: Timur Evdokimov
> Priority: Critical
> Fix For: AGING_TO_DIE
>
> Attachments: acmq01.png, acmq02.png
>
>
> We experience the following problem.
> There's 1 sender thread and 20 listener threads operating on the same queue.
> No other queues are involved.
> Message traffic goes generally OK via the queue, however Number of pending
> messages goes up one by one.
> Looking at the active customers list, the following appears (see attached
> screenshot).
> For all sessions but two, the messages are dispatched properly.
> For these two affected sessions, the "Dispatched Queue" value gots stuck at
> certain moment and doesn't deliver anymore.
> Eventually, more sessions got affected, and maybe after some hours, the stuck
> messages got delivered.
> What we tried - adding useCache="false" into <policyEntry queue=">" ... >
> tag. Didn't have any effect.
