I think what you want to do is generate a kernel dump the moment your
telnet test starts to fail (i.e. looks like it will timeout), but
before it actually times-out.
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.
