Comment (by starlight):

 An obvious objection to ulimit -n as a control is that this is simplistic
 with respect to multi-homed systems and may not always result in resilient
 behavior.  Port limits operate with respect to IP addresses rather than at
 global daemon level.  If ulimit -n is saturated, it will not be possible
 to open new control connections.
