Hello,
 
I am working on a server application. I have created a Windows Application and made a TCPListener
which keeps on listening mode. As a request comes from client it creates a separate thread for that client.
It is same for all requests from different client.
 
Now, I used to keep it running as I leave my office.
Today i saw this exception message
 
Application has generated an exception that could not be handled.
 
Process Id = 0xf50 (3920), Thread Id = 0xefc (3836)
 
What causes this exception to occur.?
 
Please reply.
 
Thanks in advance.

Solution 1

You are making a big mistake: a thread per client. Threads are expensive resources, and the number of clients is not predictable. You should not create threads in the middle of run-time. It's much better to create fixed number of threads in a very beginning and re-use them. For a TCP service, you can add just two network threads, but no less: one for accepting new connections, one more the work with all current clients.
 
For further detail, please read my past solution where I present a skeleton description of such design: Multple clients from same port Number[^].
