Since 4.6 upgrade, library scanning no longer works

[frankie64 9]

Since the upgrade to 4.6.0.5 (now running 4.6.1.0) the scan library links do not actually do anything.  I have added a number of items to the library and it refuses to pick them up, Also clicking on scan library now takes about 2 seconds to complete.  What can i do/look at?

Also seeing a very steady stream of this error in the log file:

ok, i did the following and this fixed it:

Remove Database Locks

1. Shutdown Emby

2. Change to the database location found above containing your database files

3. Delete library.db-shm & library.db-wal

4. Restart Emby

Check you server log for SQLite errors and only continue to the next step if needed
