Ivan Ravin commented on CAMEL-24619:
------------------------------------
[~tmielke] , but you right: explicitly specifying cacheLevelName=CACHE_CONSUMER
solved the problem.
> camel-jms + Artemis: the default topic consumer causes an OOM on the broker.

> Key: CAMEL-24619
> URL: https://issues.apache.org/jira/browse/CAMEL-24619
> Project: Camel
> Issue Type: Bug
> Components: came-jms
> Reporter: Ivan Ravin
> Assignee: Guillaume Nodet
> Priority: Major
>
> Maybe it's known problem. The Artemis broker creates a temporary queue for
> each topic consumer. camel-jms component can create Default and Simple
> consumer. A simple consumer is essentially a listener, and all works fine.
> The default consumer attempts to retrieve a message every second, and every
> second creates temporary queue on topic address, which live until the
> connection is terminated. This leads OOM on the broker.
> To work around this situation, you can specify in the URI
> consumerType=Simple, but default behavior is dangerous.
> It might not be a bad idea by default to switch consumer type to Simple for
> topic consumers?
> This is complex problem that affects camel-jms + Artemis topics + (maybe)
> pooled connection factory
