I have used Calibre to manage my NAS-mounted database for over a year, with no database errors, except in the past two weeks.
Still using Ubuntu 12.04 LTS [with all repository package updates applied], with my "~/Documents/eBooks_Calibre" directory on a Netgear ReadyNAS Duo, mounted using NFS.
Using sqlite3 (3.7.9-2ubuntu1.1), last updated in August 2012
Using NFS 1.2.5-3ubuntu3.1, last updated September 2012.
Have updated Calibre at least twice in the last couple of weeks, now at 0.9.33. Could something in the Calibre Python code have changed, forgetting to unlock the database?
Now get a "DatabaseException:database is locked RemoteTraceback (most recent call last): File "site-packages/calibre/library/sqlite.py", line 272, in run OperationalError: database is locked:
