Looking for root cause of NoSuchNodeTypeExceptions which are preventing AEM instances (two of them on the same server... Author/Publish) from starting successfully.
The exact pathology is a but unclear at this point. The servers were shutdown, compaction was executed and failed. Then when restarted these errors showed up and AEM was not healthy.
However, after restoring a backup from when the AEM instance was healthy the same error occurs. And now the same shows up on the Publish instance on the same server.
Thoughts?
These errors show for multiple node types: cq:Page, cq:PageContent, cq:Workflow, etc...
Error (example):
