Hi Rob, You didn't say if you had checked
/var/log/syslog Is there anything indicative of the issue there? The only indexing task I can think of is updatedb for locate, which I think is a cron.daily thing - haven't used Ubuntu for a few years so may be wrong. Which filesystem(s)? Do you have anything like recoll installed?
