Is this just happening on servers with the agent installed and any active alerts for other devices are not being retriggered?
Also have these devices been unmanaged at all? We have a case with a customer who has a weekly unmanage node schedule and this has caused alerts to be sent incorrectly. The advice in that instance was to upgrade to v12 as this includes an update to the unmanage function for sub objects.
Installation | Consultancy | Training | Licenses
Precisely, I have not seen any alerts during the 2 times that this has happened for our switches, firewalls, or non-agent nodes.
The devices are managed.
Why are the services restarting ? Any Evidence on Event Viewer -> Solarwinds logs ? Do you have an issue with the Solarwinds DB ?
If I knew, I would certainly look deeper. Event logs said this:
SMSvcHost 126.96.36.199 and Service Controlmanager (SolarWinds Orion Module Engine) both had errors within 30 seconds of each other and that was essentially it.
No issues that I know of with the DB.
I worked with a Customer Support engineer yesterday and he had me install some Microsoft Visual C++ Redistributables. According to him, not having those redistributables could cause issues as they help with the BusinessHostLayer (which seemed to be having problems) which in turn interfaces with Orion.
We'll see how it goes. Seems comparative to getting a shot of penicillin to fix an unknown health issue. It may work, but there's no guarantee.
