In my case only wtmp was corrupted.  utmp was fine.
As a further potential clue.  We don't have any VMS VAXen connected to mine,
but there is a DEC-20 that several people SET HOST from (DEC-20 --> VAX).

I'll try to arrange a test where several people SET HOST from the DEC-20
to the VAX simultaneously and see if that causes wtmp to become corrupted
again.

Keep those hints coming in!  Appreciate any clues you can offer me..todd
