Hi, The reason why the TME_WAIT state exists is to force a terminating TCP connection to stay alive after both ends confirmed closure. This wait allows: 1. delayed segments to get delivered to the right application, 2. final ACK to reach destination The reason some environments would want not to honour TIME_WAIT is to avoid the accumulation of connections in the TIME_WAIT state and the subsequent overconsumption of file descriptors. The accumulation could be problematic in fast-paced, short-lived transactional sessions. The potential risk of disabling the TIME_WAIT timer as suggested is that an application won't get the final bit of data if a segment reordering takes place. However, I really do not see how this could possibly happen in a LAN environment. Moreover, properly written applications should be able to detect malformed requests and/or replies.
