-----------------------------------------------------------
[~clebertsuconic] Actually we're not keeping the client-connection open. The
client connection is supplied to the code and is closed using a
try-with-resources in the surrounding code. We open the connection, do some
management-queue-operations, and close the connection. A while later we do the
same.

> We have a lot of problems with Artemis version 2.36.0 and higher (in a HA
> setup with shared file system). Our clients use activemq.management requests
> to see which node is active(primary) etc.
> Now from version 2.36.0 and higher there is a accumulation of these
> activemq.management queues and addresses. There is also a big increase in
> connections (amount of client connections is the same). This accumulation
> eats all the resources on the node (cpu and memory). Eventually the node give
> first a out of memory on the GUI and then node it self becomes unresponsive
> and dies (OOM kill) (no failover).
> As you can see in this graphic below (the green line), for version 2.36.0,
> there is a increase of connections (around 800). The behaviour is that
> management queues address slowly accumulate and eating resources (cpu and
> memory)
> After the gap you see version 2.35.0, which is a 'normal' amount of
> connections. Also the accumulation of management addresses and queues are
> cleaned up with default parameters
