I am seeing these alerts in vrops on multiple machines. any idea what it is and howto stop ore resolve?
Did you bother to actually look at the alert definition to see how it's built and what symptoms are triggering it?
I infer from your silence that the answer here is "no". Alerts are built with symptom definitions, and depending on how that alert is configured it may require one or more symptoms to be triggered for the alert to fire. The symptoms are the conditions that must be true or false based on metrics or properties.
You can find details on on all of the settings for these types of alerts in the vSphere Security Hardening guide.
Evaluate the 3 risk profiles and determine which one is appropriate for your environment based on the level of security and auditing that is necessary.
The alerts can be disabled in your vROps policy.
