This is simply the receiver's operating system's way of telling the 
sender - using the TCP protocol - that it can't handle incoming data 
at this rate.  I.e., you're trying to stream too much data over the 
network.


>If the images are smaller about 15 KB than it works fine.

There's your solution.  Alternatively, reduce your encoder's frame rate.

But even better: Don't use JPEG for streaming video!  JPEG is a 
*terrible* codec for streaming.  Instead, use H.264, MPEG-4, or even 
MPEG-1 or 2.
