client - server application crashes

Question

I have a client server application. The clients log in an account on my server. The thing is that my server sometimes crashes and although I have all kind of wrapped in a try-catch statement, I get no message.

The server I have implemented is here: simple threaded tcp server.

Did anyone encounter a crash like this? Is there a place that I can find an error log for the app?

I'm kind of desperate, so ANY ideas would be great. Thanks.

The application is possible to crash because of unhandled exceptions even if you have all functions wrapped in try-catch block because of multi-threading operations.

try
{
   var t = new Thread(()=>
      {
          Thread.Sleep(5000);
          throw new Exception();
      });
   t.Start();
   //t.Join();
}
catch
{
    //you can't deal with exception here
    //even though you uncomment `t.Join`
    //the application will crash even there is a try-catch wrapped
}
