Interesting! C client socket communicating with java server sockets after..

Question

Hi,
I have a client(in C) open a socket and server(in java; jvm 1.2) listening on the same port(e.g. 4444) accepts the request and establishes a socket conn. Now the sockets are kept open indefinitely. If I kill the server process and bring it backup, the client(in C) cannot communicate with the server(in java).
Why would this be happening? Aren't the server socket garbage collected?
How do I make sure that the next time I bring up the server again, the client communicates with it.
Any inputs is really appreciated.
thanks
atul.

Answer 1

Check the client is closing the connection before it stops.
I've had similar problems with JDBC before where if you don't explicitly close the connection it remains bound to the port, hence if your client only ever tries to connect to that port it will fail.
I think.
