Comments

• This APAR is associated with SPR# TMDS97VTJZ.
  Mock-reproduced in dev code, but could not create
   exact-reproduce .  Problem: The TUACache is failing to open.
   It contains conversation cache & gets created form
   bookmark.nsf ( referring from mail nsf DB ). This is root
   cause. After-effect is it tries cache verification and
   crashes. The BBLOCK vertualoffset of CIDB is zero  and causes
   Panic/crash.  Fix: Check for zeroness of virtualoffset in
   BBLOCK in nsf/index/ehashr6.c   EHVerifyCtx()    The bookmark
   cache is expected to re-Initialize cache & notes should be
   fine. But Whenever the cache open fails they would see
   rebuilding of bookmark.nsf file & cache.
