In that case, I would certainly agree that a socket should not be deleted by other than the process that created it, guessing that in this case it's the X11 Server. In checking my macOS 10.14.6 installation I see that the periodic process 110.clean-tmps is still run daily and used to clean files more than 3 days old, but that doesn't necessarily explain your issue. I see my empty .X11-unix directory (along with .font-unix & .ICE-unix, also empty) for XQuartz remains located in /private/tmp even after I quite XQuartz, so I'll have to see how long it lasts. There is a file called .X0-lock that appears when XQuartz is running, which would seem to be the socket. -Al-
