Sending messages to a topic with an inactive durable subscription will hang
producers
-------------------------------------------------------------------------------------
Key: AMQ-845
URL: https://issues.apache.org/activemq/browse/AMQ-845
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 4.0.1
Environment: Linux Red Hat Enterprise 4
java jdk 1.4.2-b28 (or 1.5.0_06-b05)
Reporter: Christopher Mihaly
Priority: Blocker
Attachments: testcase.zip
If you have a durable subsciber that is not on-line, and you have producers
sending message, eventually the server will hang on that topic.
I have attached a zip file with a junit test case and my activemq
configuration. The test case has two tests, one that creates a durable
subscription, that will succeed, and a second that starts publishing up to
100000 events, which will hang. I don't really know how to interrupt the all,
so the test case never finishes. Anyway, it does show the problem and is 100%
repeatable on my system.
The config file is set to use a SQLServer database, but the stock journal or a
derby persistence manager will do the same thing. I just switched to mssql
server because I can then see what is going on in the database. And records
are being added to the database all the way up to when the server hangs. I also
doubled the memory manager limit and moved the jmx rmi port to 1080 since I
have another server running at 1099.
