Clebert Suconic commented on ARTEMIS-3505:
------------------------------------------
It could be the case that your VM is just slow...
I would change the critical analyzer to LOG, and you should follow up on those.
The previous issue was about false reports of slow paths which we fixed...
perhaps your system just running slower .. maybe IO?
as Justin said, I would recommend regular Thread dumps and use log instead of
HALT on the critical analyzer.

> 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.
