Hello Everyone,
I have written a client/server application in vb.net 2005. It has been in development for 6 months now and I keep having a problem with the server application. It is running on a Windows 2003 server with all the latest updates. The server app runs between 3 to 7 days just fine, then all the sudden, any clients connected to it freeze, and any new clients will also freeze. The server was a console app for most of the development, but I recently moved it over to a windows service. Once I did that, I waited for it to crash again, and check the event log. This is what it said:
EventType clr20r3, P1 tdoccserver.exe, P2 1.0.0.28, P3 451161fe, P4 tdoccserver, P5 1.0.0.28, P6 451161fe, P7 dd, P8 87, P9 system.net.sockets.socket, P10 NIL
I was confused for a long time because, as I said, it would run fine, then just freeze all socket connections. The console application was responsive and worked fine. I would have to restart the server application for the clients to be able to connect. All through the development, I would get this problem, thinking there was an exception firing somewhere, so I put a Try Catch on every procedure that logs the exception to a text file. It doesn't write anything to the file when it freezes, it just quits working.
To give you a little background info, it uses the Sockets namespace to transfer text commands between the client and server. It also opens up a second port for binary data (files). The server app can be described as similar to an FTP server.
Does anyone have any ideas?
Thanks in advance for your help.
