SQLite recommends against sharing it on NFS for multiple access because locking is broken on NFS for all kinds of files, not just SQLite.
> But use caution: this locking mechanism might not work correctly if the database file is kept on an NFS filesystem. This is because fcntl() file locking is broken on many NFS implementations. You should avoid putting SQLite database files on NFS if multiple processes might try to access the file at the same time.
