Thank you for your answer!! I'm sure that this is the fragment that is failing because in my code "die" is used instead of "print" and script dies at that line.. It's possible that IO::Socket::INET tries to resolve string "127.0.0.1" or does some other (unnecessary!) query of DNS, probably I'll try to break DNS on my box to reproduce it and try to debug the IO::Socket::INET code to see what it does.. Thanks again!
