> I've been looking at TRACE logs and what seems to happen is that is that sometimes, when the client needs to create a new Socket, it sends using the same localport as the Hot Rod server port. As a result, when the client sends something to the server, it also receives it, hence it ends finding a request instead of a response. Analysis of the logs linked in the JIRA can be found in [1].<br>

> What I'm not sure about is how to fix this... There are ways to potentially pass a specific localport to a Socket [2] but this could be a bit messy: It'd require us to generate a random local port and see if that works, making sure that's not the server port...<br>

> However, I think the real problem we're having here is the fact that both the server and client are bound to same IP address, 127.0.0.1. A simpler solution could be a way to get the server to be in a different IP address to the client, but what would that be that IP address and how to make sure it always works? Bind the server to eth0?<br>

</span>You could create multiple aliases for the same loopback device, and<br>
assign a different IP address to each of them.<br></blockquote><div><br></div><div>No need for aliases, we could use directly use any IP from the range <a href="http://127.0.0.0/8">127.0.0.0/8</a><br></div><div>Just a reminder, the testsuite should be able to run on Linux/Win/MacOS so I'd stay <br></div><div>away for OS specific extra steps<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

But I fail to understand why you don't have specific ports for each<br>
