So…I set up a dev server using a db snapshot made last night (15 Jan) and a machine image created from the production server this morning. First test to create a catalog worked on dev. I then moved over to prod and was able to create a catalog there, too.
So…once I moved beyond catalog id 4, I was able to create a new catalog without error. Any guesses why this might be the case? If I had disabled catalogs, shouldn’t RT know to start at the next available ID?
