Depending on the respective runtime behavior, it could happen that the initial loading of the DB tables in the cache was performed multiple times and in parallel. The concurrent accesses then led to the `sqlite3.OperationalError: database is locked` exception as in #4951. Since this problem depends significantly on the runtimes (e.g., how long it takes to retrieve the content for a table), this error could not be observed in all installations.
