Hi managers. At the end of this is my original post. But first, thanks to the
following:

gregr@cibc.com (Greg Roberts)
Glenn.Satchell@Uniq.com.au (Glenn Satchell - Uniq Professional Services)
davidc@Aiogc.Arco.COM (dave)

Two of the suggestions were to install the recommended patches. (I reckon I
had that one coming.... :-) The other suggestion was to make sure I didn't
have any overlapping partitions (which I didn't), otherwise to try my luck at
adb. I was going to try the adb idea originally, but since I really didn't
want to ;-) I thought I'd try my luck with this list. Needless to say I went
ahead and installed the mandatory patches, and the system hasn't crashed
since. Thanks again to those who took the time to answer my question.
