Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABEND878 in QCF server address space when there are many primary
  and secondary messages.  In this case, primary messages get
  an entry in a table to save the prefix and match it to the
  next secondary. When the last secondary message arrives, it
  should delete the entry. It is not deleting the entry, therefore
  private storage below the line is getting filled.  Some
  eyecatchers in the filled storage are: $QCFMSG QCFV1R2 DDP0010
  
  The QCF V3.1 fix for this APAR is PK58502.
