After installing 2022-08 Security Update for Windows Server 2016 for x64-based Systems (KB5012170) on our Windows 2016 core server, noticed stability issues. At least once a week all devices went into an unknown state, came back, back into unknown again. With a small Ajax error window sometimes popping up on the bottom right of the page. Only a restart of the core service stabilized things for a while, until we uninstalled KB5012170. Running PRTGNetwork Monitor XL1 version 22.3.78.1873 x64

Anyone else?

Currently PRTG appears to be running okay, but early days yet. We will monitor for a week, to be more certain. KB5012170 has been uninstalled from the core server and the system rebooted. What the link is between the 2 I am not sure....
