Noticed that our http.conf file only contains MaxClients but not HardServerLimit. Is it because we are running an older version of Apache where the server limit has to be compiled with that set? We are running: 1.3.37

Our management server has set MaxClients to 2000 and it seems to work. Have been doing lots of reading and this number may cause issues when the server spikes in traffic. Most users recommend a number below 500. Any ideas?
