Problem conclusion

  • The problem is that the webserver plugin was not capturing a
    broken pipe signal. Code was added so that this signal is
    processed correctly which prevents the problem.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.2.  Please refer to the Recommended Updates
