------------------------------------------------------------------
I've uploaded a new archive containing both clients: OpenWire and Core. Please
compile and run {{classic-client.jar}} using the Artemis URL.
h3. OpenWire Client
I have run the OpenWire client on the Linux host (distribution is Red Hat 9)
against Artemis and the results were as follows:
* for 100 concurrent connection all good
* for 500 concurrent connections - exceptions occurred. Please find attached
two logs from two distinct runs where we have such exceptions
I have also tested using the Classic Broker, and I do not have any exceptions.
I tested also even with 950 connections.
I have also noticed some warnings in the Artemis log like:
{noformat}
2024-07-10 16:19:55,741 WARN [org.apache.activemq.artemis.core.client]
AMQ212037: Connection failure to /10.21.69.247:43934 has been detected: null
[code=GENERIC_EXCEPTION]{noformat}
I get this even for successful connections. Not sure if they are relevant?
I ran again for 50 connections which were all successful but I have only 30
such warnings in the log..
h3. Core Client
I have also tested with the Core client and Artemis, and all 500 connections
are successful.
However, even in this case I have some warnings in the broker log (different
than when using the OpenWire client):
{noformat}
2024-07-10 16:41:24,086 WARN [org.apache.activemq.artemis.core.server]
AMQ222061: Client connection failed, clearing up resources for session

It looks like the problem appears when using the OpenWire client with Artemis.

Artemis broker.

> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.35.0
> Reporter: Liviu Citu
> Assignee: Justin Bertram
> Priority: Major
> Attachments: activemq-clients.zip, broker.xml, classic-client_1.log,
> classic-client_2.log

> We are currently in process of migrating our broker from Classic 5.x to
> Artemis. We are currently using CMS C++ client for connecting to the broker
> {*}but the issue replicates also with the OpenWire JMS client{*}. Everything
> works fine when using non-SSL setup (on both Windows and Linux) but we have
> some issues when using SSL on Linux (SSL on Windows is OK).
> The initial problem started with the following exceptions on the client side:
> {noformat}

> The problem replicates with the following:
> * SSL on Linux. Problem does not replicate if non-SSL configuration is used.
> Also does not replicate on Windows (regardless if SSL or non-SSL is used)
> * two Artemis instances running on the same Linux host (problem does not
> replicate if there is only one Artemis instance running)
> * problem also replicates if there is one Artemis Broker and one Classic
> Broker instance running on the same host
> * *problem does not replicate with two instances of Classic Brokers. So it
> is specific to Artemis broker*
> * when testing with both Classic Broker and Artemis Broker, the client
> connections using the Classic Broker were fine. Only those using Artemis
> Broker were failing
> * Artemis clients are also running on the same same host with the Broker.
> Basically both client and server are running on the same host
> * there are many connections done in the same time to the broker (25+). If
> there are only few then the problem does not happen
> * example of connection URL used by the client (the other instance just
> uses a different port)
> *ssl://linux_host:61617?keepAlive=true&wireFormat.MaxInactivityDuration=0*
> * Broker configuration file attached (just mangled the SSL stuff and name of
> the host). The other one is similar (different ports)
> When monitoring the successful connections I found out that usual connections
> took less than 0.5 seconds to succeed. I was unable to find any successful
> connection that took more than this.
> Looking to the broker logs we are unable to find any relevant message when
> the connection fails.
