[awah]

[CODE]http://img301.imageshack.us/img301/5328/closewait0lw.jpg\[/CODE\] 1. what does "close wait" means? 2. what does "fin_wait2" means? i understand that these are socket status but - what do they mean? the socket is waiting for server? the socket is shutting down but waiting for certain event to happen before it's allowed to shutdown? - what situations causes them? - it seems that the socket is waiting for something, how can i stop the close wait/fin_wait2 and shutdown the socket? (gracefully or forcefully) it seems that sockets on "close wait" and "fin_wait2" on my program are the ones with problems please advise
