If you see the “Port 5053 in use, waiting…” message in your debug log (or on the console), that means there’s already an RLM license server running on that port.

5053 is the default port for RLM licenses, so if you already have a RLM-licensed product (for example, from the Foundry or from Exocortex), then port 5053 is already in use.

The solution is simple: edit your .lic file and change the port number on the HOST line to something like 5052 or 5060. Do not use port 5054. 5054 is used for the RLM Web Server, and you’ll get a “Cannot bind Web Server port 5054, exiting” error if you try to use it for the license server.
