Error description

  • In Rational Developer for System z - RDz - v8.0.3.3, logon
    sometimes took
    so long (due to an unresponsive threadpool), that the client
    timed out and
    closed the socket. This lead to the Broken pipe messge
    encountered by the
    RSE daemon. A second logon attempt is successful.
    
    Recreate Steps:
    
    1) disable single.logon (to increase chances of hitting the
    problem)
    2) have a threadpool eat up a logon request before going in
    timeout
    3) have a client with a timeout shorter than the threadpool
    timeout and attempt a logon
    
    Local fix: none
