Hello 
I'm using arduino uno + ethernet shield to send sensing data to my serve for every 10 seconds.
the problem is that after 30~60minutes, arduino stop working and when I checked arduino board, It's not sending any data seeing tx is not blinking anymore.
why is it?
below is code that I sending sensor data to my server
if (client.connect(serverName, 80)) { //starts client connection, checks for connectiong
client.println("GET /settingtemp/?temp="+String(inpc.inpd.temp)+"&hum="+String(inpc.inpd.humi)+"&bat="+String(inpc.inpd.bat)+" HTTP/1.1"); //download text
client.println("Host: xxx.herokuapp.com");
// client.println("Connection: close"); //close 1.1 persistent connection
client.println(); //end of get request
}
else {
Serial.println("connection failed"); //error message if no client connect
Serial.println();
asm volatile (" jmp 0");
}
and Serial monitor is also stop with below weird last word..
