But if you use it for something else, it would be usefully to have more the 40 connections, becuse I was just scripting an IRCD on mIRC and found the same problem. If there are more then 40 á 50 connection directly trying to join/part or quit the server, mIRC will crash.
I made an bot to, for port scanning, but this one is only scannen joining users for openport (proxy-ports) But if there are to many people connecting add one time.. My bot will crash and all other function's off the bot will be offline :S and that's so bad!
