Winsock send recv buffer size

Question

I'm writing a MFC app to implement a client/server scenario and using Win socket for that. I can send/receive a small message e.g. "hello". Also, I tried with buffer of size 1000. However, when I increase its size further, it just hangs. Doesn't even throw any error.

Any idea about what the problem could be? Is there any restriction on the maximum size of buffer I can send/receive in winsock? I'm a newbie in this and never used winsock before.
