Comments

• Serviceability improvements for overlay detection of high
  SHARE region on a 4gigabyte (xxxxxxxx_00000000) boundary.
  If an overlay is detected on storage starting at a 4giga-
  byte boundary, it is possible to encounter a program check
  or an ABEND0C4 when this APAR is applied.
  In addition, ABEND04E 00E20012 will occur when Db2 makes an
  unexpected storage request that is 4 gigabytes or more.
