:I've been running 3 loops of mirroring wget -m on the apache manual,
:with the fetched page deleted in between, MaxClients=256,
:MaxKeepAliveRequests=0. There is one loop runned localy.
:
:There are more than 4000 connections in TIME_WAIT, more than 4000 sockets.
:
:The server responds very well and there are no delays.
:
:Tomorrow I will try MaxKeepAliveRequests to an impossibly high number to
:generate long running connections and see how it copes.
:
:I welcome suggestions on what test to run as I am no expert in neither
:os nor networking.

Have you adjusted the portrange? Do these:
sysctl net.inet.ip.portrange
sysctl net.inet.tcp.msl
sysctl kern.ipc.maxsockets
sysctl net.inet.tcp.recvspace
sysctl net.inet.tcp.sendspace
You may also have to lower the MSL on the originating machines to reduce
the number of sockets being held in a TIME_WAIT state.
(default is 30000ms)
sysctl net.inet.tcp.msl=15000
