After a restart of the tilerator / tileratorui services, those services stopped listening on their respective ports (TCP/6534 / TCP/6535). Systemd reports the services running. Logs show errors related to mapnik (see below). I suspect that we did not update the tilerator version running on maps-test2003 to correct version.
Note that maps-test2003 is used for testing (as the name indicates) and does not carry any user traffic, so this isn't high priority.
