A very subtle race condition. Your are closing the connection server side without waiting for the client to complete. If your client finish before s.
Close, you will get the right answer, if the server finish first, you will get Errno::ECONNRESET. Which mean the client lost the connection while working.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
