muthuma-

I don't think the F_GETFL or F_SETFL warnings are part of your current problem. See Re^5: sending data over TCP channel using POE::Component::Server::TCP on this. I've tested the following example under windows and unix (various). It still works even with the warning messages under windows.

I've been asking for so much help on POE stuff lately, here is what I can give back. Hope it helps.
