Need to keep restarting FreeRadius service

12 Jan 2023


      I have setup my Unifi network to connect to a Raspberry Pi 2 hosting
FreeRadius 3.2.0 with MAC authentication. That all seems to work now,
however I've run into an issue where it seems the FreeRadius service
needs to be restarted fairly frequently, at least multiple times a
day. From what I can tell, the Pi is fine and there's plenty of
storage and resources. Restarting the service allows anything that was
having issues to connect, such as if it's been disconnected for a bit
(e.g., my phone when I go out and come back) but even devices that
don't leave the house and stay on sometimes lose connection until a
service restart. I know I could probably setup a cron job that
restarts the service every 30 minutes or so, but I wanted to check if
people had ideas on how to fix it. Here's my freeradius -X output with
one example of a device connecting successfully.
