Arduino YUN server crashes after few hours!

Question

I have made a simple server using the YUN SERVER and CLIENT Libraries./ The server runs on a loop and waits for a client to connect. After connection it sends the client a simple message and then disconnects the client.

#include <Bridge.h>
#include <YunServer.h>
#include <YunClient.h>

#define PORT 6666
YunServer server(PORT);
int pin =13;

void setup() {
  Serial.begin(115200);
  Bridge.begin();
  server.noListenOnLocalhost();
  server.begin();
}
void loop() {
  YunClient client = server.accept();
  if(client.connected())
  {
    digitalWrite(pin,HIGH);
    //startup
    startup_msg(client);
  }
  else  
    digitalWrite(pin,LOW);
    delay(500);
}
void startup_msg(YunClient client)
{
    client.print("SAndTerm");
    client.stop();
}

Well this code runs smoothly for few hours. But after that, it stops responding to any client request. I guess the server crashes. I have to restart the YUN to get it working again.

Is there anyway I can run this without it getting to crash? Well I want it to be running just like a normal server would.

Updating your YUN might solve this problem. It is recommended to update it after you buy it because they usually come with old firmware. Make sure its up to date. Here a link on how to do this

Another thing to try is to add delay(50); at the end of the loop() function. It prevents the processor from doing lots of work.
