Dropped tables are not deleted from filesystem

Hi, I’m using Manticore 5.0.2 and I’ve got an issue. We create RT indexes on the fly during search queries in the system to speed certain system searches up. These are dropped immediately after use, but I’ve just looked in the /var/local/manticore/data folder and there are literally thousands of the old table folders still there, all containing a lock file.

Is this a known bug? I did try searching and couldn’t find anything about it.

The table names are all based upon a guid, so they’re all unique, hence why we haven’t had any db name clashes, but I’d rather not have thousands of directories in the data directory!
