Hi.
But do we already use SO_KEEPALIVE on the socket layer?
Also I am not really sure socket was closed on the server end. TS said he could see server backend in the idle state. Also backed server did not fail, so unless there were some network glitch we should have received tcp reset.
BTW: Are there any stateful firewalls or NATs between server in client?
Best regards, Vitalii Tymchyshyn
