TIME_WAIT is an often misunderstood state in the TCP state transition diagram. It's a state that some sockets can enter and remain in for a relatively long length of time, if you have enough socket's in TIME_WAIT then your ability to create new socket connections may be affected and this can affect the scalability of your client server system. There is often some misunderstanding about how and why a socket ends up in TIME_WAIT in the first place, there shouldn't be, it's not magical.
