  *                      when a queue manager reconnects to a    *

  ****************************************************************
  When a queue manager connects to a CF structure, CSQERAS1 is
  called to recover the queue manager's connection to the
  structure if it had previously disconnected from the structure
  due to a failure. If CSQERAS1 reads an eUOWD from the admin
  structure that relates to a structure other than the one that
  is being recovered, it can incorrectly attempt to write it
  back to the admin structure with an updated version number.
  The 5C6-00C51167 abend occurs if the eUOWD happens to be
  deleted between CSQERAS1 reading and attempting to update it,
  causing the write to the admin structure to fail unexpectedly.
  

Problem conclusion

Temporary fix

Comments

• CSQERAS1 has been corrected so that it does not attempt to
  update eUOWDs that relate to work on CF structures other than
  the one that is being recovered.
