I dont think it is repeatable :-( In the 10 minutes preceeding the message,
the system was processing a lot of incomming mail almost constantly, so there
would have been some load, although the system was still quite responsive
(32Mb of ram on this box).
I was thinking of panic'ing the system at that point in case it happens again
to get a crash dump, but i have a problem in that this is an ISA machine with
an ah1542, so i would only get the first 16Mb of a dump (i think) :-( I think
maybe we need some bounce buffer hacks in the scsi dump code... either that
or buy a decent board :-)
Cheers,
Karl
