  ERROR DESCRIPTION:
  ******* (Do NOT alter/erase this or next 3 lines) *******
  * EQUIVALENT ABSTRACT:
  LIC-TAPE DSPTAP _SAVRST HANGS SYSTEM ON D/T3570 OR D/T3590 TAPE
  SAVED USING THE SAVSAVFDTA COMMAND
  Customer saved data to a D/T3570 tape drive using the
  SAVSAVFDTA command and then tried using the DSPTAP *SAVRST
  command to view the tape and the system hung up with solid
  CPU.  A MSD was taken and it was determined that task LDLOIM
  was taking all of the CPU.  This could also occur with D/T3590
  tape drives.  The MSD also showed that the system was trying to
  go down with SRCB6005121, SRC0002000A, SRC00100013, SRC00000002.
  LOCAL FIX:
   Don't use DSPTAP on tapes saved using the SAVSAVFDTA command.
  PROBLEM SUMMARY:
  Customer saved data to a D/T3570 tape drive using the
  SAVSAVFDTA command and then tried using the DSPTAP *SAVRST
  command to view the tape and the system hung with solid
  CPU.  A MSD was taken and it was determined that task LDLOIM
  was taking all of the CPU.  This could also occur with D/T3590
  tape drives.
  PROBLEM CONCLUSION:
  When using D/T3590 or D/T3570 (devices which support the
  USEOPTBLK(*YES) parameter on save commands) if a tape file
  created by the SAVSAVFDTA command is followed by any other tape
  file the DSPTAP *SAVRST would cause the system to go into a
  solid run loop.  The problem has been corrected.
  TEMPORARY FIX:
  COMMENTS:
  MODULES/MACROS:   #LDLOOC  #LDMODE
  SRLS:      NONE
  RTN CODES:
  CIRCUMVENTION:
  When doing a DSPTAP *SAVRST only process one tape file at a
  time.  Do not process the entire tape in one command.
