ECO KIT SUMMARY:

An ECO (patch) kit exists for PAGE_MANAGEMENT.EXE on OpenVMS VAX
V5.0 through V5.1-1.  This kit addresses the following problems:

  o  During image termination, VMS deletes the P0 virtual address
     space of a process.  The system crashes with a PGFIPLHI bugcheck
     at address MMG$DELPAG+0014D.

  o  A pagefile becomes fragmented and fills up with blocks marked
     "allocated", but not used by any process, the system, or global
     sections.  This can cause the following symptoms:

     *  Response time decreases the longer the system is up.

     *  Increased CPU time for the SWAPPER process.

     *  PAGEFRAG and PAGECRIT messages are displayed on the console
        when the pagefile(s) have 50% or more of their space free.

  o  The system may crash with a FATALEXCPT bugcheck.
