At this time I am not sure about this one. Amanda ran normally AFAIK this
morning.

The machine does not appear to be affected, but I did just find this,
in /var/log/messages: (I think this is the one I posted)

So it did not repeat the Ooops this morning. I wish I had more clues to offer.
Let it ride as is for another 4 or 5 days, during which time I may have a good
excuse to reboot & restart this -rc5 from scratch. Or maybe someone else might also
note it, but if not watching the log, I think its otherwise silent & may go by
un-noticed.

Thanks Rafael.
