How do I diagnose problem?

[rkimber at ntlworld.com]

I just noticed that bogofilter was taking up 99.9% of one of my CPUs for
what seemed like a rather long time.  It might of course only have been
a minute or so, but I've never seen this before. No doubt I did the
wrong thing, but I killed the bogofilter process.

The questions are how do I find out what went wrong and have I done any
damage? Version 0.93.4, DB 4.2.52, Suse 9.1 opteron.
