It's a bit strange to be picking a port in that range for a server process.  I would go for the range up to 49152 since those are fixated.  You'd have to accept that 5353 has been taken, but at least any problems claiming a port are always the same and not something you would resolve with trying again or rebooting.  Let's not turn UNIX into Windows, shall we?  ;-)
