John,prefork and worker are mutually exclusive. When apache is compiled, one is picked. In order to change the MPM, apache must be recompiled.

On a related question (and not to hijack this thread too much...)...In the file apache2.conf there are two sections that determine the server operation, prefork MPM and worker MPM. Where (how?) is the decision made to set either mpm_prefork_module TRUE or mpm_worker_module TRUE? It is my understanding that these approaches are mutually exclusive when Apache is launched. Correct? -John On Wed, Mar 11, 2009 at 12:00 PM, Frank Gingras <francois.gingras@xxxxxxxxx> wrote:Andrew, Well, WinNT uses a different MPM model. There is a parent process, and a 'child' process that has internal threads, visible from mod_status. On linux, those would show up as separate processes.

Open your config files, and see what those directives are set to. Idle workers are processes which are not responding to any HTTP request at the moment. Frank.

And about server-status: Parent Server Generation: 2 1 requests currently being processed, 63 idle workers What's mean parent server generation and idle workers?
