Maximum buffer size is an optional argument that specifies the
    maximum number of octets to be used for event processing of this
    sink.  The current value is displayed in the buffer size status
    attribute. You can specify a size smaller than the
    implementation's default, provided it is still sufficient to hold
    the events lost event. If the value specified is inadequate for
    the events lost event, an "insufficient resources" exception is
    returned.  It is recommended that you use the default buffer size,
    which is 16384.

    Example:

    create event dispatcher sink local_sink -
         maximum buffer size 16384
