Details:

Hello.
Using LwIP 2.1.2 on TI TivaC MCU in NO_OS mode.
My code sends a packets via TCP/IP to the application on a computer at the
following rate:
11 12-byte packets at 100Hz and 25 12-byte packets at 1Hz. So overall data
rate is 13500 bytes/s.
After about a minute of such traffic I got and error callback with ERR_RST
code at my side and in the same time I got WSAENETRESET error during recv() at
computer side, which means some keep-alive activity on a connection was
failed.

What could be the cause?
