Here is one idea.  There was a problem with Release 2.2.2 and back
regarding the dskinit program when the system was installed.  Caused
a nasty little problem, formatted the driving using 112 cylinder 
instead of 110!!  This caused the swap file (end of drive) to be
partially located over the non-existent space.
This could cause some rather weird problems and various panic conditions.
It is fixed in 2.2.3 (xnx116 or xnx117).
..
This is just one idea.
But this one took a bite out of us, so thought I would share it with you
in the hopes it may prevent another user of the catastrophre we had.
