Timothy Bish commented on AMQ-7210:
-----------------------------------

Have you closed the connections you created to communicate with that broker you 
keep restarting?

> AMQ slows down due to high number of stale ActiveMQ Connection Executor 
> threads

>                 Key: AMQ-7210
>                 URL: https://issues.apache.org/jira/browse/AMQ-7210
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 5.15.9
>            Reporter: Sahil Patayar
>            Priority: Critical
>         Attachments: ActiveMQ_Connector_Executor_threads.JPG,

>
> We have an enterprise application, and we are using embedded ActiveMQ.
> We are currently using 5.15.2 version. We tried the latest(5.15.9) version, 
> but the issue still persists.
> ActiveMQ Connector Executor threads are being created in ActiveMQConnection 
> class.
>  
> ActiveMQ Connection Executor threads are not going away even after restarting 
> the broker programmatically. Threads keep increasing and after bouncing the 
> Broker, they don't go away.
>  
> Steps to reproduce:
> 1. Run load test on ActiveMQ.
> 2. Take thread dumps
> 3. Stop the Broker multiple times
> 4. Take thread dumps again.
> Result: Compare the thread dumps, executor threads from the previous dump 
> will be present in all next dumps.
