I had the experience of having a 3b1 at home for awhile for work related
computing and had the same experience you have had.  After one month
of fooling around with it, here are my results and a conclusion :

  1. On my machine, it ALWAYS happens when uucp transfers
     are being done.
  2. First was using the non-HDB uucp, so got the HDB uucp, it does
     does the same thing.  By the way, I re-loaded the system at least
     10 times during that month.
  3. If you are lucky to be still on when it is happening, look around in
     /bin  /usr/bin  /etc with  ls -l  and notice the STRANGE file
     permissions and file sizes etc. (You must do this quick tho!!)
     The machine is quickly trashing files until it has trashed files
     that are needed to keep itself running!!!!
  4. I finally got a message (mail) from the system as it was
     thrashing itself to death.  Seems it was running out of SWAP
     space, and removing processes to regain SWAP space.
  
            Consulsion, this thing needs more SWAP space!!

       Problem: I have not found a person that can tell me in
                easy terms how to re-configure the hard disk to
                get more swap space, and
                YES IT WAS CONFIGURED FOR MULTI-USER !!!!


  For the person on the att.sys.unixpc  AT&T group:

       Now you have THREE machines with the same problem, so I guess
       I CAN KNOCK the machine now    HUM ?????

    As you guessed, I work for AT&T, and the AT&T news group did
    not have any answers either.

   PS:   AT&T service replaced the drive 3 times in response to
         this problem, (found out the person that had the machine
         before me was having strange problems also).  I GOT
         RID OF THE MACHINE, it was useless to me.  This machine
         did not have a combo board, in fact I removed the DOS-73
         board to try in isolate the problem, no luck there either.

  Lots of luck
