It often will, TCP's reliability only goes so far. Take the case where you're using a GUI MUA on a modem-connected machine. You click the 'close' button on the MUA window and then the 'disconnect modem' button. Almost certainly, the packet containing the LOGOUT has been sent before you manage to click the 'disconnect modem' button, but if that packet is lost, the PPP connection is probably down before the retry would happen. --Arnt
