I think this is just used to check if the connection to the database (or in 
case of sqlite, to the file) can be estabilished and that Digikam can make 
the modifications there. So it's probably not an issue.

And this means that there are too many folders in the collection, so a new 
directory could not be added to the list of watched folders. That means that 
new items (or new folders) appearing inside that can not be monitored for 
changes (new files, removed files).
