pre-2.0.30 and PPP, swap-related crash

While running pre-2.0.30, a PPP connection, popclient, and an IRC
client, I had a little OOPS. I currently have two swap devices with
different priorities, one an IDE disk and the other a SCSI disk. Since the
system has 64Mb of RAM and wasn't heavily loaded, it was not swapping
heavily at the time of this event. Any clues would be appreciated.
