Cause
In Active-Passive configuraiton POA agent should run only on the currently active node. To handle this situation Windows high availability cluster is configured with only Generic script role.
This script handles POA agent start when needed (previous active node failure for example).
Errors like above mean that POA agent is trying to run on node when it is not needed (another node is active for cluster roles).
Resolution
Check what node is actually active with:
[PS] C:\Windows\system32>Get-DatabaseAvailabilityGroup -Status | fl name,primaryactivemanager
Name : Group-DAG01
PrimaryActiveManager : DAG01
Name : Group-DAG02
PrimaryActiveManager : DAG02
Name : Group-DAG03
PrimaryActiveManager : DAG03
Name : Group-DAG04
PrimaryActiveManager : DAG04
Name : Group-DAG05
PrimaryActiveManager : DAG05
If node in question is not in the list open Administrative tools > Services > POA agent
Set startup type to Manual and stop POA agent on the node.
When it will be needed POA service will be started automatically by generic script role.
