  When submitting wsadmin script jobs to an admin agent that
  will be run on multiple managed servers, scripts might fail
  intermittently and inconsistently with an
  InstanceNotFoundException, probably followed by a
  NullPointerException and CWWSY0612E message.
  Management trace of the admin agent will show that the
  objectnames of mbeans being invoked on one server are
  incorrect and contain the attributes of mbeans from a differen
  server.  As a result an  InstanceNotFound  exception is thrown
  when the mbean cannot be located on the target server.
  

Problem conclusion

• A thread safety issue in the code has been corrected so the
  problem no longer occurs.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.4  Please refer to the Recommended Updates
