Error description

  DB2 R202 R302 R210 R220 R230
  AN ABEND0F8 CAN OCCUR IN DB2 INSTRUMENTATION FACILITY COMPONENT
  CODE (IFC DSNWTRC DSNW...) WHEN DB2 TRACE DATA IS BEING ROUTED
  TO SMF AND THE INSTALLATION HAS SMF EXIT IEFU84 CODED TO FILTER
  SMF RECORDS.  THE ABEND INDICATES AN SVC WAS ATTEMPTED UNDER
  INVALID CONDITIONS.  THE ABEND IS VALID AS SVC'S ARE NOT ALLOWED
  IN THE EXIT ROUTINE UNDER THE ENVIRONMENT USED BY DB2 TO PROCESS
  SMF RECORDING.  AN EXAMPLE SITUATION THAT CAN RESULT IN THE
  ABEND IS A USER OR OEM VENDOR PACKAGE THAT USES EXIT IEFU84 AND
  ATTEMPTS A GETMAIN OR FREEMAIN SVC FOR A WORKING STORAGE AREA.
  THE PSW IN THE ABEND0F8 DUMP MAY POINT INTO THE EXIT ROUTINE
  CODE.  THE PROBLEM CAN BE BYPASSED BY TURNING OFF ALL DB2 TRACES
  HAVING DESTINATION SMF.  THIS INCLUDES THE ACCOUNTING AND
  STATISTICS TRACE.
  ADDITIONAL INFO: THE ABEND0C4 AND ABEND0F8 SYMPTOMS CAN OCCUR
  IN COMBINATION OR SEPARATELY.  IT MAY BE DIFFICULT TO DETERMINE
  THE SUPPLIER OF THE SMF USER EXIT (IEFU84 OR IEFU85) CODE USING
  JUST THE PSW ADDRESS OR REG14.  AN ADDITIONAL POINTER TO THE
  OFFENDING MODULE CAN BE FOUND AT OFFSET X'7C' IN THE SMCA (WHICH
  IS POINTED TO BY MVS CVT OFFSET X'C4').
