Local fix

Problem summary

  • An error in code designed to log an FFDC if not all files are
    closed at the end of a transfer caused the agent to sometimes
    log an FFDC for this issue when no files had been left open.
    There is no functional impact on the agent for this problem.
    
    USERS AFFECTED:
    All

Problem conclusion

  • The code which checks if all files have been closed has been
    altered to ensure that it does not throw false negatives.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 7.0.4.2.
