When I probably recommended  MaxSpareThreads == to MaxRequestWorkers was due to Apache httpd with third party modules not restarting gracefully, that along to MaxConnectionsPerChild 0 would prevent HTTPD from trying to restart them.

Where did you get this?

Also I keep wondering why people assign so many processes, StartServers 16? In a threaded mpm?

Why not just assign just 2 or even 4, and assign 100, 200 worker threads each?
