From time to time the following error occurs in DeltaShell:
SQLiteException occurred SQL logic error or missing database at most 64 tables in a join
This indicates that Nhibernate is fetching too many different objects (tables) at the same time. Note that it doesn't matter at all if there is any data in those tables. All that matters is basically how many plugins are loaded and how complex the relationships between the framework and their classes are.
