  services with the audit and error log files, and trace
  files if available.
  ------------------------------------------------------

Local fix

Problem summary

• USERS AFFECTED: All using the LUA API.
  
  PROBLEM DESCRIPTION:
  "Message type 1 discarded" is logged in sna.err when an LUA
  application is retrying (issuing RUI_INIT) while the link
  is inactive.
  
  PROBLEM SUMMARY:
  This error message is caused by a narrow termination race
  in the code processing the RUI_INIT failure. It is not
  harmful, and it does not cause any other problem.
  

Problem conclusion

• Code has been modified so that this message does not get
  logged when this termination race occurs.
  

Temporary fix

• sna_v5router64
