[RESOLVED] Socket/Port remains open after app crashes

Posted on 16th Feb 2014 07:03 pm by admin

I'm having this problem with a networked app in vb.net.

If the program exits normally the port closes fine, however, if it crashes sometimes it remains open and I am unable to close it. The next time I run the program it is unable to open the port because it is already in use. Here's the exception:
10048: Only one usage of each socket address (protocol/network address/port) is normally permittedAny ideas on how I can reclaim this port, or how I can close it?
I tried using the reuse address socket option

Code: SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, 1) but that just opens the port again and does not close the old one. see this netstat output:

TCP PCISERVER:14000 PCISERVER.cpwpci.cpwgroup.net:0 LISTENING 4320
[System]

TCP PCISERVER:14000 PCISERVER.cpwpci.cpwgroup.net:0 LISTENING 5808
[System]

TCP PCISERVER:14001 PCISERVER.cpwpci.cpwgroup.net:0 LISTENING 5808
[System]

TCP PCISERVER:14001 PCISERVER.cpwpci.cpwgroup.net:0 LISTENING 4320
[System]

As you can see once the program exits the ports remain opened by the System process.
I don't know of a way to stop them from listening besides a restart.
