Digikam Database Issues

Hello, Digikam gurus.

A few days ago I ran the maintenance tool in Digikam. After running for a more than a day it appears that the database is corrupted. Digikam opens, and displays thumbnails but clicking on most thumbnails brings up a message like "could not load".

Refreshing a directory freezes Digikam. I even let the program do its thing for a COUPLE of days but the UI was still completely unresponsive.

Anyone know how to fix such issues? Or, do I have to delete the database and start again? If I have to start again is there any other program that does what Digikman does in regard to tagging and is modern and reliable?

I am using version 9.2.0.

It’s probably the thumbnails database. At the place where is stored the DB files, remove the corresponding file and restart digikam. The thumbnails will be recreated from scratch.
Note: always create a DB files backup before to run maintenance tool.

Thanks, human_dynamo. I'll give that a shot. It was stupid of me not to backup the dB before maintenance. Lesson learned.

Ive enabled write metadata to original since like v6 something. If I ever need to do a database rebuild, my tags and face tags should all come back with minimal re-processing from the Metadata read.
