  DFHCQ0259I  CEKL SET: KILL request issued for task number 09984.
  DFHME0139  (Module:DFHMEME) Message DFHSM0001 has been

  * PROBLEM DESCRIPTION: CICS continues to report being SOS even *

  ****************************************************************
  CICS becomes SOS.  To free up storage CEKL is used from the
  console to KILL a number of tasks.  If one or more of these
  KILLed tasks are suspended waiting for storage, their suspend
  queue elements remain in the suspend chain even though the tasks
  have gone away.  As a result CICS still believes it is SOS even
  though storage in the DSA is now available.

Comments

• The Storage Manager recovery routine has been modified such
  that, if driven for a task which is currently suspended the
  suspend is completed.  As a result the suspend queue elements
  are removed from the queue.
