Justin Bertram commented on ARTEMIS-3505:
-----------------------------------------
At this point I think it would be best to utilize the [ActiveMQ users mailing
list|http://activemq.apache.org/contact] rather than this Jira. The only thing
we've established so far is that the critical analyzer is haling the broker
which is not necessarily abnormal. If we can confirm or strongly suspect that
there is a bug we can open a new Jira with all the relevant details. I'm going
to close this one.

> Hello All,
>
> We have noticed the same problem which we reported earlier with 2.17 and
> were told that it would be fixed in 2.18 version. We have recently moved all
> our environments to 2.18 version and can see the problem still exists across
> all of our env's.
>
> We have below architecture in respect to activemq master/slave setup.
> {noformat}
> producer/consumer --> Apache QPID (1.14) --> Artemis 2.18 (master/slave)
> {noformat}
> Basically, we see our master and slave brokers going down abruptly with below
> log. I have also attached the thread dump for analysis to see if anyone can
> spot anything, for sure we can see it is to do with some concurrent
> deadlocks. Please go through the attached logs and suggest any feedback, if
> any.
> The log that is causing the issue is highlighted below, as soon as the broker
> prints this, it prints The Critical Analyzer detected slow paths on the
> broker. *and therefore*, AMQ224079: The process for the virtual machine will
> be killed.
