Error description

• An ABENDS378 RC0C can occur near IQCCIN10 + x'0BDA' or IQCCIN20
  + x'06F2' when restarting IMS and when the DIAGxx IGVUNCOND
  trap is set.                               REASON CODE=0000000C
  
  Additional Symptom:
  The timing at which the problem occurs can cause a different
  reason code as follows:
   An ABENDS378 RC18 or RC14 can occur near CSLSDR20 + x'0574'
   when shutting down IMS and when the DIAGxx IGVUNCOND trap
   is set.

  ****************************************************************
  QCF extensions running in the IMS CTL region tries to release
  storage for some work areas using the wrong PSW key during
  initial and termination processing.
  It usually does not notice this defect because it issues the
  STORAGE RELEASE macro with the COND=YES option. An ABENDS378
  occurs when the DIAGxx IGVUNCOND trap is set.
  

Problem conclusion

• QCF has been changed to release storage using the correct PSW
  key.
