Hi!
We are using TomEE 1.7.2 with message driven beans and ActiveMQ 5.11.1.
In general there are about thirty threads that handles the message driven
bean activities (JmsResourceAdapter-worker- - 1, ...,
JmsResourceAdapter-worker- - 30).
But from time to time we can see that every mdb execution results in a new
thread (JmsResourceAdapter-worker- - XYZ), the threads in the thread pool
are not reused any more.
The amount of available threads is constantly about thirty but the threads
are new and old ones disappear.
Increasing / Decreasing the thread pool size (ThreadPoolSize parameter for
Resource ActiveMQResourceAdapter) seems to have no impact.
Is there an idea why this could happen and how to prevent it?
Best regards,
Thomas
