System bombs.

[Small Moose Ltd]

I'm getting more than my fare share of system bombs on my iBook recently.
Usually I will suffer lock ups, freezes, hangs or whatever, but a system
bomb is pretty unusual. The funny thing is that this morning I ran Disk
First Aid 8.6 and Techtool Lite extensively (that it to say I ran both a
couple of times). Techtool fixed and restarted a minor error, and I ran it a
further time to check that all was well and it was.

Then, just now I get another bomb. All I had been running at the time was
the Mac OS and Entourage. It was on battery power and I just went and
plugged in the AC cord, phone line and finally my hockey puck mouse and the
bomb flashed up saying something like a 'queue error'. Fortunately it
allowed me to close down Entourage and restart under my own steam, as
usually the moment a system bomb message appears, the machine locks up.

I will fix this, but is there information available on why we get system
bombs and the different types of bombs? I'm using MacOS 9.0.4
I am aware of the 'Sad Macs, Bombs and Other Disasters' book but I was just
wondering if there was a web resource that details the same kind of thing?
