  * PROBLEM DESCRIPTION: CICS abends with message DFHRM0002,     *
  *                      after an AKEA abend (0C1) in DFHDTUP    *
  *                      and an ASRA abend in DFHFCRC.           *

  ****************************************************************
  If an EXEC CICS rewrite command is issued against a record in
  recoverable User Maintained data table and the data space used
  by CICS for that data table is already full then a NOSPACE
  condition is returned. This will result in a backout element
  being created although it will not be marked as inflight. Within
  the same unit of work, the same record is deleted or replaced
  successfully, this again creates another backout element but
  is marked inflight. The unit of work is then committed via a
  syncpoint. At this time the backout elements are processed and
  this results in the old version of the record being deleted
  twice. This error is detected and a deliberate program check
  is issued by executing a half word of zeros at eye-catcher
  DTDMFREE in DFHDTDM. This program check results in message
  MsgDFHRM0002, and brings CICS down.
  R1 at the time of the 0c4 may contain a value of 000C0FB8 or
  similar.

Problem conclusion

• DFHDTRM has been changed so that if the UMT is
  recoverable then the backout element will be discarded
  after nospace error if it is not marked inflight.
