Hi All,
I've just got hit by an OutOfMemoryError: unable to create new native
thread issue. I've switched UseDedicatedTaskRunner to false which
appears to have resolved the issue for now but I have a feeling I'm
just masking a deeper problem.
I have the following set up:
2 ActiveMQ brokers configured as a network of brokers
Several applications that use
- a Spring JmsTemplate with a PooledConnectionFactory
- a Spring DefaultMessageListenerContainer that uses a regular
ConnectionFactory. The DefaultMessageListenerContainers are set to
CACHE_CONSUMER
- a static failover broker URL for both the JmsTemplate and listener
container to the two brokers
In the applications themselves, I'm getting this:

In the brokers I'm getting this:

I'm also getting a lot of these in the logs:
FailoverTransport.doReconnect | Successfully connected to tcp://xxxxxxxx:xxxx
any ideas?
