Today my system (7.9) has decided to rescan automatically, several
times, for no apparent reason - I was not even playing anything, just
getting ready to do so. I see nothing at the start of this on the log.
However, when the scan finishes and custom-scan and other plugins get in
on the act I get warnings like the one below. There is no hint of a
cause of the initial rescan. I don't know if the 'database is locked'
error is a server issue or a plugin issue.
I've not seen anything like this before. I've only updated one plugin
recently (squeeze2upnp) and I switched that off, but that didn't help.
How can I diagnose this?

I have also seen some strange network errors such as:
