    Max limit is a feature that puts an upper hard limit on a number of open
    connections. This is a safety feature to avoid unintentional opening of a
    huge number of connections.

    Now, this is a known bug reported here:
    http://sourceforge.net/tracker/index.php?func=detail&aid=595385&group_id=481

    This should be fixed soon.
