Domino users:
Do NOT put these PTFs on:

When I dropped my Domino servers for maintenance and tried to bring them back up again 
LNT0928
Error 2 occurred while running the Domino server. 
2 -- The Domino server stopped running because an exception occurred.
2 -- Check the job log of the Domino server for possible errors. (nothing but this)
Nothing on the Domino console.
"What changed?"
Those PTF's.

success!
HCL Domino (r) Server (Release 12.0.2 for i5/OS)
Not sure if the following applies.
**Domino 12.0.2 Fix Pack 2 or higher recommended but not required.
I may open a case on Monday but why bother now because if it's not a system supporting a power grid for the eastern seaboard and a bank of life support machines I will catch endless grief trying to get them to work on it over a weekend.  Especially since I have a workaround.
