Hi in apache i am checking on preforking mpm modules, In my apache configuration there seems it going against theory on certain odd conditions. If you are setting StartServers=x and MinIdleServers=x+2 then it has to start the apahce with x number of childs and it has to settle down to x+2 value on server(Be informed that there is no load), Instead of settling down to x+2 it comes as x+3. Now if you are getting confused, lets take some values for x. Say under prefork.c StartServers=3 MinSpareServers=5 Then theoritically it should start 3 (httpd PIDs) and then it has to scale to 5httpd(PIDs), instead it prefork 6childs. which is totally wrong against the docs. If there was a load accepted, it could have preforked and settling back down. if startserver=4 and Minspare is 6 then it preforks 7 instead of 6childs. Any explanation to this much appreciated.
