When a program uses RPC for socket communication, it may stop working for no apparent reason. If you quit and start the program again, it works correctly, but may stop working again. If you check the output of the netstat -n command, Netstat reports many open connections in a CLOSE_WAIT state with the port that the program is using. This is a sample of the output from the netstat -n command:
Active Connections  Proto  Local Address          Foreign Address        State...  TCP          CLOSE_WAIT  TCP          CLOSE_WAIT  TCP          CLOSE_WAIT ...					
This problem occurs because RPC uses a socket that is called a SyncSocket to optimize data communication. If the Syncsocket is closed incorrectly by the program that loaded the RPC transport, RPC enters an error loop that it cannot return from. RPC always assumes that the SyncSocket will always be a valid socket, and does not have any recovery mechanism to handle situations in which another function closes the SyncSocket.
