    * USERS AFFECTED: All users of Websphere Message Broker        *

    ****************************************************************
    * PROBLEM DESCRIPTION: The error reported is BIP3150 failing   *
    *                      with EINTR 'Interrupted system call'    *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    WebSphere Message Broker's HttpRequest Node performs a
    select() operation to select the socket file descriptor to
    write on.
    On linux systems, when a large number of select() calls is
    made, one could fail with EINTR and result in the HttpRequest
    Node call failing.
    

Problem conclusion

  • WebSphere Message Broker has been modified so that it retries
    the select() call when there is an EINTR error.
    

Temporary fix
