MantaRay opens 3 TCP connections on the same port

Another problem with mantaray: We have "a lot" of PCs in a network, our p2p messaging software uses MantaRay (which we plan to replace with something else). On some PCs the task manager shows CPU at 100% when this application runs.

We tried to investigate that with TCPView, and found that these PCs open more than one TCP connection from the same client TCP port to the same server port.

This problem occurs on relatively slow machines, with Windows XP SP2 (or SP3).

开发者_C百科Does anybody know of similar problems? Is there a way to avoid it? Are we doing something wrong?

A first solution was setting TcpMaxConnectRetransmissions to 0 in Windows Registry, but I don't think it's the right solution, and could have other consequences. I think it shouldn't happen, and I see that as a Windows XP bug.

That's not possible by the rules of TCP. Netstat is known to produce phantom entries, which might explain it, maybe TCPView is getting its info the same way. It is quite impossible.
