Repeatedly loses and then regains some sensors

Can I disable the discovery worker for a device?

The reason is, I have a device that repeatedly loses and then regains some sensors. As a result, I keep losing my own settings (warning levels).

Or is this caused by something else?
I don’t think this is due to my LibreNMS installation. I have the same problem with similar devices. Many others work perfectly fine.

Here is the event Log:

Thanks.

Try to increase SNMP timeout. Some devices need a quite long time to answer as the SNMP-queries do not have highest priority and may be delayed.

Very good idea, I will try that.
Thank you!
