Hello all, I am reaching out for help because unifi is currently getting the best of me. I have 2 unifi servers in a colo. Both are running on linux, both were installed the exact same way with Glenn R.'s scripts. Both servers have 12cpus and 30G of ram. Both are running 8.0.28 (a requirement for now). Server A has 1226 devices and 6100 clients. Server B has 1069 devices and 7000 clients. Server A is stable and has no issues. Server B will chew it’s resources over the course of about 12 hours and remain in a high use state until I restart it. After it maxes out it no longer reports clients and the gui becomes very slow. I have followed the guide for high scale on the unifi forums, I’ve tried spliiting the db to a separate server, I’ve given Server B 50G of ram, I’ve tried various other fixes from the unifi forums. I have edited the properties file to account for the ram and also added the other recommendations from forums. Does anyone have any insight? Is 8.0.28 just unstable? Any response would be greatly appreciated, I can post whatever from my system.
Is server B public facing?
If it were me I would stand up a brand new server and upload your config file to it. Then migrate the IP or if you used FQDN then update that so your clients know where the server is.
Take a look at the incoming traffic and syslog to see if something is coming in a much higher rate than normal.
