----------------------------------
Summary: 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
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
