when i added the ServerLimit line in httpd.conf, on restart apache it says Syntax error on line 36 of /usr/local/apache/conf/httpd.conf: Invalid command 'ServerLimit', perhaps mis-spelled or defined by a module not included in the server configuration this is the error i get WARNING: MaxClients of 312 exceeds compile time limit of 256 servers, lowering MaxClients to 256. To increase, please see the HARD_SERVER_LIMIT define in src/include/httpd.h.

Well, this means that apache was built (compiled) with 256 MaxClients limit and there is no other way to increase this value than recompile apache. To check HARD_SERVER_LIMIT value compiled: # ~apache/bin/httpd -V | grep SERVER_LIMIT -D HARD_SERVER_LIMIT=256 Similar discussion: http://www.linuxquestions.org/questi...-issue-310627/ change src/include/httpd.h: #define HARD_SERVER_LIMIT 256 with #define HARD_SERVER_LIMIT 1024 BTW, on our H-Sphere hosting we already have: # ~httpd/bin/httpd -V | grep SERVER_LIMIT -D HARD_SERVER_LIMIT=1024 Good luck,

As anato said, you need to edit the source code and rebuild apache. Maybe, you should look for an admin to do that. In general,what do you need to do is to optimize your apache server, so you don't need to rebuild. Yet, there is a reason why the default maxclients value is 256, its related to the RAM memory. Use the search at the top of webhostingtalk to find out some articles about optimizing apache. Ok?

Are you sure you did not start another web server? (es. IIS on Windows) I had the same error ... Then I turned off IIS! Now is OK.
