BUG: JMS consumer hangs while producing profusely

Help! I have a transactional JMS consumer invoked by Camel for messages on "testQueueA" -- it needs to produce/send thousands of messages to the JMS queue "testQueueB". Depending upon how many messages need to be sent, this scenario hangs. This happens when talking to ActiveMQ via TCP. I wrote

Help understanding memory usage/limits

I could use some help understanding memory usage & limits in activemq. 5.3.1 is what I'm running, fwiw. 1. Out of the box, in activemq.xml is commented out. I'm passing ACTIVEMQ_OPTS="-Xmx2048M ...". What is the default behavior in that case? Does that mean activemq will take advantage of th

Re: Help understanding memory usage/limits

? Is there a way to allocate a specific memoryLimit to individual specific queues & topics? That would probably be smarter in my case if such a thing is available. Sorry to blast more questions at you...I'd just like to have a better understanding. Thanks! Dan Gary Tully wrote: >

I'm experiencing an issue with ActiveMQ 5.3.1 broker. Here's my setup: - 1 queue that experiences heavy usage (the only relevant destination in this case) - 80 concurrentConsumers on the queue - consumer.prefetchSize not set (default = 1000, I believe) Occasionally my service sees a spike in tr

Re: 100% CPU spike with ActiveMQ 5.3.1

BTW, I forgot to mention one possibly key piece of info. The consumers run on a different server. ActiveMQ runs on its own dedicated server. So it's using TCP, not VM, in case that matters. dcheckoway wrote: > > I'm experiencing an issue with ActiveMQ 5.3.1 broker.

Performance issue with Camel multicast in 5.4.1

In the process of upgrading from 5.3.2 to 5.4.1, I've encountered a new, major performance issue. I make use of Camel's multicast in order to replicate messages from one queue out to four other queues...snippet from conf/camel.xml:

BTW...I forgot to mention that in order to rule out Camel being responsible, I tried the same test in 5.4.1 with Camel 2.2.0 jars (5.4.1 comes with 2.4.0). No difference. -- View this message in context: http://activemq.2283324.n4.nabble.com/Performance-issue-with-Camel-multicast-in-5-4-1-tp295
