ESP8266 freeze when TCP connection intempestively close.

[cyberpablis]

I use a TCP client socket on a ESP8266 to connect a server socket on a PC, and send periodic packets. If from Windows, I deactivate the network card on which it receives the packets and activate it again, the device freezes. I've tried to change UIP_CONNECT_TIMEOUT in uipethernet-conf.h, but has not effect. The ESP8266 stays frozen forever, like it's in an infinite loop. Does not respond, does not refresh the embeded display (SH1106), nothing.
