APAR status

• Closed as program error.

Error description

• You are running CICS transaction server v4.2 and have IPIC
  connections between CICS and CTGs. You start experiencing
  the following error messages in the TORs:
  DFHIS0002 A severe error (code X'0686') has occurred in module
  DFHISXM.
  DFHIS0002 A severe error (code X'0206') has occurred in module
  DFHISIS.
  DFHIS0002 A severe error (code X'0687') has occurred in module
  DFHISXM.
  The TORs and CTGs need to be recycled to resolve this problem.
  Review of the dump shows that the CISR task has issued the
  initial receive which returned some bytes of data. This was
  enough to do the XMAT ATTACH for the mirror task before issuing
  another receive to get the remaining bytes. The CISR task got
  suspended switching from the QR to the SO TCB.
  The mirror started and the DFHISIS INITIALIZED_RECEIVER call
  was issued by DFHISXM INIT_CLIENT. This results in the task
  being suspended on an IS_RECV waiting for the CISR task to
  receive the remaining data.
  The CISR task is resumed and the remainder of the data is
  successfully received. The ECB that the mirror is waiting, is
  posted complete. The task got suspended waiting for new input.
   When the mirror task then resumes, the INVALID_STATE is
  issued.

  ****************************************************************
  A DPL request with data size larger than 60K is received in
  CICS from a CTG client over an IPIC connection. The CISR task
  is notified and an ISSB is obtained for this request. CISR
  then attaches a mirror task to handle this request. During the
  process of the mirror task, a deferred abend is detected and
  CICS then frees the ISSB and terminates the mirror task.
  However the rest of the data for this request is received and
  handled in CISR task which causes some fields in the freed ISSB
  is incorrectly updated.
  
  When a new request is received, CICS gets an ISSB for this
  request. If the updated ISSB (contains incorrectly residual
  value) is used here, this request can not be handled by CICS
  successfully which causes an exception and DFHIS0002 message
  being issued.
  

Problem conclusion

• CICS has been changed so that the ISSB can not be incorrectly
  updated after it is freed.
