Prevent panic mode crashes by used port #2
Description
The panic mode code should be as resilient as possible to ensure that panic mode code is finishes executing all the way (logging fatal errors, notifying other systems, etc.)
One problem in the example code is the static port on which the panic mode files are hosted. If this port is in use, the master thread will die. This error should be caught and the application could try to, for example, listen on port + 1. Ideally, the port used should be logged in the console.
A PR for this issue can be made by whomever feels the need to improve this example.
