Hello comunity,
normally on artemis broker start the artemis.log is created if not present
or the output is attached to artemis.log, if the file is there.
On a broker restart after a failure we faced a recreate (overwrite) of the
present artemis.log with artemis 2.41.

Hello Nazar,
why not use the multi-tab feature of the browser?
I have created a little batch file like this
start http://host1:8160/
start http://host2:8160/
...
It is still anoying to log in multiple, but once this is done it is fine
for me.

Hello Team,
I have a question regaring Artemis.
We have two different clusters, that run more or less independently.
But for some events and requests there should be a transparency between
the clusters.

I'm using Artemis 2.30 and have noticed, that the connection count

Did I understand something wrong?

to my experience nio on the broker is absolutely cool..
It is faster and decoupling clients.
On the client side it makes no difference.

Hi John,
did you look at the Message Time To Live (at the point where the reply
gets sent)?

expire.
And if you ron non persistent messaging, these temp queues might not have
any listener any more, but still waste memory

Hello Richard
8k should be enough sockets. You must at least re-login or reboot to make
this active.
Did you verify with ulimit -n ? What did you get?
btw. After=network.target is sub-optimal.
After=network-online.target
is better.

Hi Folks,
Thank you for the answers.
I was re-implementing our application driver with MQTT Version 5 libs and
found it way better to use.
But I'm affraid there will be some impact on the broker side.
And if you do not want to break things, both protocols must be supported
for a while.
