Minor Description
First of all, sorry if this is the wrong place to post this.
This has nothing to do with Observium, but rather with the clients it monitors.
I am hoping that someone has a solution to this problem.
We have a handfull Ubuntu clients that we are trying to monitor via SNMP v3.
They are mostly Ubuntu 20.04 LTS which uses NET-SNMP 5.8.
The problem is that the SNMPD service dies pretty quickly after we have setup the monitoring...
We have of cause googled the problem, and it seems to be a know issue which should have been solved in a later release (which is not yet released on Ubuntu 20.04 (or 22.04))
If anyone has fixed this issue, please share the knowledge 
For now we have setup a cron that restarts the service every hour (which some times isn't enough)...

This is completely not Observium issue, you should use Ubuntu (and/or Net-Snmp) issue trackers.
I can only suggest to use SNMP v2 (instead v3) if there is known issue with v3 snmp.
