Topic (non-durable) gets unsubscribed even though the TCP connections to
Active MQ are alive (observed on Windows 2008 server)
-------------------------------------------------------------------------------------------------------------------------------
Key: AMQ-2994
URL: https://issues.apache.org/activemq/browse/AMQ-2994
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.2.0
Environment: Windows 2008 server (Enterprise edition)
Reporter: Dip Narayan Sarkar
In the concerned product, one Web Application deployed on Tomcat server does
non-durable subscription to topics to Active MQ.
Both Active MQ and Tomcat are running on WIndows 2008 server (Enterprise
edition)
On one of the 2008 servers, it is seen that one topic subscribed by Tomcat got
"UNSUBSCRIBED" even though the tcp connections from Tomcat to Active MQ are
alive. The messages published by the corresponding topic is about 15 - 20 per
minute. Tomcat logs DO NOT have any relevant exception trace.
Neither there are any exception traces in ActiveMQ logs
The system has been running for 15 days. On 16th day we found that the JMS
messages are not reaching the Web App, upon debugging process thru JConsole, we
found that the Tomcat's subscription are not present.
This happened for the 2nd time on a Win 2008 server.
Same code base is running fine for > 25 days (with larger flux of messages) on
more than one Win 2003 servers.
Need some pointers on possible root causes and if any known issues are present.
