APAR status

  • Closed as program error.

Error description

  • When calling web services, customer is intermittently getting
    the following error:
    
    javax.xml.ws.WebServiceException: java.io.IOException: Async IO
    operation failed (1),  reason: RC: 76  A socket must be already
    connected.
    
    Setting com.ibm.websphere.webservices.http.connectionKeepAlive
    to false resolves the error messages, but customer is looking
    for a way to resolve this without setting connectionKeepAlive
    to false.

    ****************************************************************
    When calling web services with a JAX-WS client application,
    the following error may occur:
    javax.xml.ws.WebServiceException: java.io.IOException: Async IO
    operation failed (1),  reason: RC: 76  A socket must be already
    connected.
    

Problem conclusion

  • The JAX-WS client was not honoring the CONNECTION HTTP header
    value of CLOSED and attempting to re-use the connection.
    The client now honors the CLOSED value and will not attempt to
    re-use the connection.
    
    Note that there are other causes for this same error message
    and trace should be used to verify the CONNECTION HTTP header
    value was CLOSED prior to our attempt to re-use the connection.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.21 and 8.0.0.2.  Please refer to the
