    Hello. I have installed RabbitMQ 3.2.2 on two nodes as "Generic
    Unix" distribution from the website. Even though it appears to start
    successfully on both with "Starting broker... completed with 0
    plugins.", on one of the nodes, which is without doubt part of the
    older Linux distribution (Centos 5.10 with kernel 2.6.18, Erlang
    R12B from base repo), the *-sasl.log file is filled with the
    following:<br>

    This may not be a problem in itself, but I am debugging a problem
    where a client connecting to this particular RabbitMQ node, is
    unable to complete a handshake (The client is Celery). This may be
    Celerys fault of course, but on the other RabbitMQ node where the
    log doesn't list the above, the connection works fine, so I am
    suspecting the above having something to do with the handshake
    failure. <br>
    <br>
    Meanwhile, I will try to juggle between different Erlang versions to
    try to get to the bottom of this, but maybe some of you guys can
    spot immediately what went wrong here? <br>
    <br>
    Thank you.<br>
