SharePoint 2010 and Project Web app error provisioning

Had a strange error the other day with provisioning a Project Web Application (PWA).  

The errors didn't really say much except these three event log items.  Errors below. 

To resolve I have to create the PWA site on another environment and then do a back up and restore to a site collection in the environment that was breaking.   then run the provisioning on central admin.  Everything works great after.
