just apache httpd (WARNING: MaxClients of ... exceeds ServerLimit value of 256 servers)

Using httpd 2.x.x (source-code) and then need to increase MaxClients > 256 for mpm_prefork_module.

<  IfModule mpm_prefork_module >

    StartServers          5

    MinSpareServers       5

    MaxSpareServers      10

    MaxClients         257

    MaxRequestsPerChild   0

<  /IfModule >

# apachectl start

WARNING: MaxClients of 257 exceeds ServerLimit value of 256 servers,

 lowering MaxClients to 256.  To increase, please see the ServerLimit

 directive.

Found Warning... 

Solving this case when we use HTTPD compiled from source-code, increase size.

- Go to Source-Code PATH

# cd SOURCE_HTTPD

# cd server/mpm/prefork

- Modified prefork.c file.

# vi prefork.c 

Old:

#define DEFAULT_SERVER_LIMIT 256

New:

#define DEFAULT_SERVER_LIMIT 1024

*** Increase to 1024*** 

- Reinstall httpd 

# cd SOURCE_HTTPD

# make clean

# make 

# make install

Or

# pwd

SOURCE_HTTPD/server/mpm/prefork

# make clean 

# make 

# cd SOURCE_HTTPD

# make install

- Start httpd again.
