Local fix

Problem summary

  • In rare cases a racing condition during LQMA startup could cause
    a MQCONN request to fail with RC 2195. This was caused due the
    starting agent sending its registration request before the
    Execution Controller has finished the creation process. The
    request is then rejected since the Execution Controller does not
    accept requests by unknown agents.
    

Problem conclusion

  • The WebSphere MQ product code has been changed to prevent this
    racing condition.
