Hello All, I am looking for some help in troubleshooting an ActiveMQ installation. We are running ActiveMQ 5.4.2 on Linux on Java 1.6.0.25 using Java Hot Spot 64-bit Server VM. We're using KahaDB as our persistent store and we have pre-fetch values set to 3000 for these consumers. We're running about 30 consumers per thread across 6 machines. So, each machine has 5 threads consuming messages.
We're having some pretty big issues with ActiveMQ in our environment that we can reproduce in our QA environments, but not on command. The issues tend to happen over time. They are happening at least once a week, sometimes up to 3-4 times a week. The issue is the following: - On the ActiveMQ web console, we see a given queue has pending messages. If we browse the queue using the web console, there are no messages in the queue. Our application is also not receiving any messages to process and if we use a JMS Browser, no messages are visible. - If we restart Active MQ, the messages come back. We are able to see them in the browser, the application starts receiving messages and a JMS Browser can see messages. How can I begin to troubleshoot this issue? Its worth mentioning that we are not seeing any exceptions in the ActiveMQ logs around the time the issue starts occurring. Thanks so much for the help! -- View this message in context: http://activemq.2283324.n4.nabble.com/Pending-Messages-but-Browsing-Queue-Shows-No-Messages-tp4222713p4222713.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
