PK07588: ABEND30A ERROR DURING FREEMAIN SYS CODE = 30A-24 DUE TO X'4040' OVERLAY OF PLPA BY IQCXWRUL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• During QCF UNLOAD, ABENDS30A or different abends can occur in
  a rare case when moving a record into the input/output area to
  write it to the UNLOAD file (4 extra more bytes {x'4040'} are
  moved).  This destroys the aligned storage therefore different
  errors can occur.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of QCF. In some cases a 30A- error *
  *                 may occur at end of UNLOAD procces.          *
  ****************************************************************
  * PROBLEM DESCRIPTION: In some cases UNLOAD ends with error    *
  *                      30A - error on FREEMAIN call.The reason *
  *                      for this error is that 4 bytes more     *
  *                      than the message's length are moved to  *
  *                      the otput buffer, overlaying the        *
  *                      storage that follows the output         *
  *                      buffer.This happens on rear occasions , *
  *                      because of the aligning the buffer      *
  *                      storage on double word boundary.        *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The program has been changed to move the exact number of bytes
  to the output buffer.
