How to start more Apache servers? in Uniform Server - Windows Posted January 14, 2009 · Report reply I'm running 3.5-Apollo and using the Apache server to start/manage ong-running local processes via proc_open() (up to 3600 seconds). But once I kick off 2 of these processes, my Apache server won't respond to any other requests - it just queues them up until one of the servers is free. Looking at the XP task manager, I only see 2 Apache.exe processes at any given time. Plus, my dual CPU usage is only around 25%. How do I start more servers to handle the other requests? I'm running the following in my httpd.conf: <IfModule mpm_winnt.c>ThreadsPerChild 250MaxRequestsPerChild 0</IfModule> michael.
