Out Of Memory errors detected on your server

This morning I woke up to an email alert saying

Event: Fix Common Problems - Server

Subject: Errors have been found with your server (Server).

Description: Investigate at Settings / User Utilities / Fix Common Problems

Importance: alert


**** Out Of Memory errors detected on your server ****


Remote logged on to have a quick look and everything now seems fine but it's the first time I have had this error since using unraid.


Memory usage was just under 50% at the moment but something clearly happened around 04:30 for an alert to be sent.


At around 03:00 my unifi docker was updated

Event: Community Applications

Subject: Docker Auto Update

Description: unifi-controller Automatically Updated

Importance: normal


But this has never caused issue like this before.


I have attached diagnostics, hoping it is just a one off http://cloud.tapatalk.com/s/5fb0fd621c32a/server-diagnostics-20201115-0954.zip
