This article mentions that root cause is node's cache was not in sync with the database.
Can someone help how to prevent this node cache sync issue? Our Pega cluster is hosted in AWS as EC2 instances. Cluster has 4 nodes (2 are categorized as background nodes and 2 are categorized as web user nodes). We have auto scaling process as part of which nodes will be brought down to 2 during 8 PM and again nodes will be brought back to 4 nodes at 8 AM.
Would this constant node updates can cause this sync issue? How this can be prevented?
