Seems as if your server has not enough ram.

Default seems to have fixed ...

bumped up MaxClients from 256 to 4096 in prefork and worker seems to have made it happy
also set ServerLimit to 4096 as well
so far unable to reproduce the error.

I stayed with Apache2 and not nginx because this is a true compiled executable CGI. any chance nginx might actually run it? might be willing to give it a chance

Have you considered to install munin and monit on the server to monitor and visualize the server usage?

Here is a short guide from nginx wiki about running a cgi script with nginx:

http://wiki.nginx.org/SimpleCGI

But I did not try that, so I dont know if it works. It might also be that apache is not the problem here and the ressources are taken up by the cgi script itself.

In any case, if you want to try nginx I would recommend to do this in a virtual machine first as you cant easily switch your apache setup to nginx without reinstalling the server. You can download a perfect server virtual machine which works with virtualbox here from howtoforge.

Default munit etc

I asked if you that it was ok to just --force

Mots likely the logoff is initiated by the client. Test another client e.g. the fireftp plugin for firefox to see if it has the same behaviour.

Default just for your amusement

it turns out the ftp client logoff was due to my software trying to use passive mode - and I had forgotten to put a big block of holes in the firewall (30000-50000) to accomodate that.
once the firewall was opened the problem evaporated
