[ https://issues.apache.org/activemq/browse/AMQ-845?page=comments#action_36874 ] Anders Bengtsson commented on AMQ-845: --------------------------------------
If you give it a higher memory limit it will accept a few more messages before blocking the producer. It seems to keep stuff in memory, making it very limited in the queue depths it can handle. We're also completely blocked by this, since our application requires large pending queues. > 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 > Assigned To: Rob Davies > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/activemq/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
