Oops,
I just realised i missed the reply, sorry! I've only just got back to
looking at this again.
sqlite3 from the command line is fine.
The log message about the busy timeout is from the motion service in linux.
In PHP i've set "$db->exec('PRAGMA busy_timeout = 5000;');" to try and
help, but not sure if it's made any difference yet.
How can I do the same for motions sqlite3 access?
Originally (before PHP) i was using bash scripts to generate the HTML
and delete unwanted video entries from the database, and that worked
fine, but it was really slow.
I started re-implementing it in PHP, which is a lot faster, and of
course only generates pages when I request them, which is a lot more
efficient, but only since using PHP have I started having locking problems.
Thanks,
Chris
