  ****************************************************************
  IMS wait in DLI address space due to invalid intent list address
  after reloading a PSB which has no database PCBs.
  There was a loop attempting to follow an intent list chain
  because of an invalid address in PDIRDMBS, the intent list
  address/TTR.
  

Problem conclusion

• HP Sysgen did not completely clear the PDIRDMBS field, which
  caused a loop when the last byte of the field contained a
  non-zero value.
  Code has been modified to correct this problem.
