[sqlite] DatabaseError: database disk image is malformed

I'm trialling a centralised SQLite database to store process automation metadata with a known, small, fixed number clients (around 10) as part of a Jenkins CI system running on Windows. The clients connect occasionally and run simple, quick (sub-second) SELECT queries and even less frequent
