[RESOLVED] Winsock fails after 1 hour

[VictorN]

...
Problem:
After exactly 1 hour, my client closes with the socket error param code = 10053
My server too errors out at the following line
result = WaitForMultipleObjects(object_count,wait_objects,FALSE,210000);

Well, this "code snippet" doesn't help us to understand which (exactly!) line of your code causes the error 10053.

And FYI, MSDN description of this error is

WSAECONNABORTED
10053

Software caused connection abort.
An established connection was aborted by the software in your host computer, possibly due to a data transmission time-out or protocol error.

So at this place I agree with Paul:

Unless we have your program and source code, there is no way anyone can answer your question with anything but guessing
