I still get these errors, regardless of what I change them to. I noticed that Apache only spawns new servers in two's compliment fashion, so I've changed these values accordingly: MinSpareServers 32 MaxSpareServers 48 StartServers 64Joshua - I understand what the settings mean. My reasoning behind these settings is that Apache would be able to quicker respond to a request if it already had a child waiting for the connection. If for some reason this site got an additional 40 hits in one instant, Apache would deal with those by sending them to children, and then when that is established, it would create more children in anticipation for new connections. Regardless, where might I be able to find more information about this error? I'm very curious now.There is some additional comments on this stuff here: http://httpd.apache.org/docs-2.0/misc/perf-tuning.html#runtime The problem with your settings is the lack of flexibility you are giving to apache. Setting Max/MinSpareServers to similar values will always result in apache needing to fork and kill processes frequently. If you want to have lots of spare serving capacity available, then all you need to do is increase MaxSpareServers (and perhaps StartServers if you want this capacity available immediately). Joshua.
I understand your argument, but these values are far from similar.I guess I'm just looking for high performance information concerning Apache, this being v1.3.33.
