If I do the same test without threads it works fine...

Really? Could you show me your non-threaded code that allows you to be both server and client talking through the same port and the same IO::Socket::INET handle at the same time?

Because that is what you are trying to do in the above code.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
