PM86353: ABEND0EC3 WITH REASON CODE 20F00400 IN LIBERTY SERVER

APAR status

• Closed as program error.

Error description

• The customer was using running a liberty server on z/OS with
  an active Angel process.  The server was configured to exploit
  z/OS extensions.   Once of the z/OS native services abended
  while running in an authorized environment.   The cleanup
  routine for the terminating task may take an ABEND EC3 with
  reason code 20F00400.

  ****************************************************************
  An ABEND EC3 RSN=20F00400 may occur after an authorized routine
  has abended on the current thread.  Authorized routines are
  dispatched using the dynamic area from a task-level structure
  (TGOO).  The task-level dynamic area is marked in-use while
  the routine is under dispatch.   The routine abending may
  leave the in-use flag on within the task-level structure.
  A cleanup routine (serverAuthorizedTaskCleanup) running under
  control of a task-level resource manager will attempt to use
  the dynamic area and issues the ABENDEC3 with 20F00400 when it
  detects that the in-use flag is on.
  

Problem conclusion

• The entry linkage for serverAuthorizedTaskCleanup has been
  modified to allow the in-use flag to be on and compensate.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5. Please refer to the Recommended Updates page
