> One user saw a case where a single mis-programmed client was overloading the
> server with connections - the client was creating a huge number of sessions
> to the server. This caused all of the fds on the server to become used.
> Seems like we should have some way of limiting (configurable override) the
> maximum number of sessions from a single client (say 10 by default?) Also we
> should output warnings when this limit is exceeded (or attempt to exceed).
