APAR status

• Closed as program error.

Error description

• This FREEMAIN failure with code x'0D07' in module DFHSMMF' still
  occurs even with PM55512 applied. It appears that this
  failure in mod DFHEIIC (UK77330) +x'32AA' occurs because
  TCZICADP is zero.

  ****************************************************************
  A remote EXEC CICS START performed by DFHEIIC by an application
  using adapter data produced the same symptoms as those fixed by
  UK77330, even though that PTF is applied.
  The reason for this is that TCA field TCZICADP, which was
  correctly set on upon entry by DFHEIIC, has been overlaid by
  zeroes by another domain's use of the same storage area during
  processing of the EXEC CICS START. This leads to DFHEIIC issuing
  an invalid FREEMAIN of storage location zero.

Problem conclusion

• UK77330 UK77488 UK78671 UK79075
  DFHEIIC has been changed such that, just ahead of the FREEMAIN
  of ADPTFLDS storage, if field adapter_ptr is non zero, we now
  move its contents into tczicadp, to compensate for the
  possibility that tczicadp may have been inadvertently overlaid.
