Hi Torsten Thanks a lot for your answer.
Even though I hadn't seen it, it doesn't really help me: indeed, it's not the message consumers themselves who run out of memory, but the thread in which they run. Starting from the OutOfMemoryError, the message consumers don't consume any message anymore, while the topic looks like keeping these messages (for the consumer to consume them at some point in the future). Is there some way to reduce the time the topic waits for the message consumers to actually consume their messages? The only option I can think of currently may be to reduce the time to live of the messages, however we also have a durable topic subscriber for which the messages have to stay around longer, and as such we can't reduce to lower than the current value. best joseph -- View this message in context: http://activemq.2283324.n4.nabble.com/OutOfMemory-in-messageConsumer-thread-activemq-running-out-of-memory-tp4175801p4176141.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
