I could not find any reference if the version of apache compiled for centos 5.x has support for more than 256 clients in apache's maxclients.

I think 256 is the _default_ not the maximum.

From the Apache httpd 2.2 docs

<snip> For non-threaded servers (i.e., prefork), MaxClients translates into the maximum number of child processes that will be launched to serve requests. The default value is 256; to increase it, you must also raise ServerLimit. </snip>

The Centos httpd does not seem to be compiled with anything that would restrict that. Others may know better ....
