I have set up SNMP sensors on a new QNAP NAS equipment (TS-470 Pro). The SNMP service has been activated on the NAS. After being set up, sensors collect informations properly for an hour or so and then fail with a 'No response' status. When I have a look at the timeline, sensors go up and down, switching between No Response and correct status. I can't make it stable at all, and I don't have this kinf of problem with another similar NAS (TS-453 A).
Thanks for help!
