Subject [jira] [Created] (AMQ-6240) Producer cannot be terminated when slow consumer is detected
Date Mon, 11 Apr 2016 10:00:29 GMT
Ken Hall created AMQ-6240:

             Summary: Producer cannot be terminated when slow consumer is detected
                 Key: AMQ-6240
             Project: ActiveMQ
          Issue Type: Bug
          Components: Connector
    Affects Versions: 5.13.2
         Environment: The test was run using an out of the box install of ActiveMQ 5.13.2
on Windows 7 Professional (64 bit). 

The java version used was jdk1.8.0_60
            Reporter: Ken Hall

There is a discussion relating to the bug here -
Test code to reproduce the problem  has also been uploaded to this discussion.

We have  a situation where we have a producer which is feeding a slow consumer.
The consumer belongs to a third party so we do not have control over the broker configuration.
We would like to terminate our producer but we find that we cannot do so. We can set the timeout
on the connection and we then trap the timeout exception. The problem is that when we try
to close the session it attempts to rollback but cannot do so as the rollback blocks.

We have created a small test that is included in the zip (mentioned above) of an Eclipse project.The
zip includes three classes. Call the main method of RunTest to run the test. The activemq.xml
used is in the root directory of the project. 

The program will timeout after 51 messages and attempt to close the session. 

It eventually locks in this line: 


in the rollback method of the TransactionContext class.

We believe that the most sensible solution to this is that the rollback should respond to
the same timeout as the connection.
