Seems that the certificates have no impact whatsoever.
Anyway, {*}j{*}ust for your information: * *I have run some tests today on my
laptop using *Windows 10 64BIT* (this laptop is not in the datacenter with the
Linux VM where the other tests are running so I am rolling out environmental
issues)

With Classic Broker I can run 500 concurrent connections without any problems.
But with Artemis Broker, starting with 400 connections onwards I am
encountering connectivity issues. On the server side I see errors like:

h3. CORE Client
When running for 500 concurrent connections there are no connectivity errors.
However, I noticed that in this case the client process is stuck at some point
up until the first connections are being realized. The CPU is 100% and the
process does not move for a couple of minutes. Then responses are coming and
everything is going back to normal.
However, in case of *OpenWire* client the connection errors are retrieved much
faster which is strange. I was expected some more waiting time until errors are
thrown.
As a conclusion, I am not sure what is going on :( but I tent to agree that
there might be some resource issue in the middle as you have earlier stated:
{noformat}
Perhaps Artemis needs more CPU, more memory, faster IO, etc. to deal with the
concurrent load you're putting on it. It may be that Classic has a built in
bottleneck due to the way it's designed that's throttling connection attempts
internally which helps it deal with the load.{noformat}
Anyway the errors are not encountered on every run. Sometimes I can run 500,
600, 700 connections without any errors while sometimes I got errors from the
first run. It is the case on Linux VM as well.
I am using the same certificates in Artemis and Classic hence the problem is
not there. I have also tested with OpenSSL provider and I have pretty much same
behavior. Indeed sometimes it connects a little bit faster but I still have
errors for some connections as above.
I have created these java testers as I though there is a concurrency issue on
the server side but actually our problem does not involve so many concurrent
connections. When we replicate the issue with OpenWire Negotiation timeout I do
not think we have more than 20 active connections to the Artemis broker. The
issue is quite random and very hard to replicate manually. Basically we have
some automated regression tests using our software that behind the scene launch
some Broker connections and performs various operations (connect,
sending/listening data, etc). From time to time we are unable to start a
session (as the error we actually have is not during connection step but when
creating a session). If it were a connection step then it wouldn't have been a
problem because we have a retry mechanism there but we do not have that when
creating a session and I do not think that is possible (if the session cannot
be created due to broken pipe then I guess the whole connection is broken)
PS. I will start again the Java tests on Linux playing with tls version to see
if there is a CPU problem.

> 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)
> * *problem does not replicate with 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.
