Excuse me, I don't know nothing about the expiration problem, but
AFAIK the Server Level 3.1.2.0 is NOT Y2K-Compatible. Therefor I
really don't understand why any is upgrading to this level. The latest
ptf is for 3.1.2.40. We are running our Servers on 3.1.2.20 (OS/390,
AIX, Solaris, NT) for months. Your mvs guys were applying really old
code. But watch - the expiration processing changed after 3.1.2.20.
