That indicates that your calibre library is either being written to by multiple processes or is on some broken filesystem such as a networked disk or an external disk with a non-native filesystem

My library has always been on an internal hard disk - so not a networked or an external disk.

My Calibre Server was on - accessing the library through Calibre Companion on my Android Tablet. But now that I have reinstalled Calibre 2.60.0 so server is not on.

But still the startup error.

OK, realised the problem was because my internal disc where the calibre library resided had got near full.
Sorry for bothering.
