I'm testing my server to know how many concurrent connections it support. I configure my mpm_prefork.conf this way:

# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# MaxRequestWorkers: maximum number of server processes allowed to start
# MaxConnectionsPerChild: maximum number of requests a server process serves

<IfModule mpm_prefork_module>
    StartServers             5
    MinSpareServers       5
    MaxSpareServers      10
    MaxRequestWorkers     100000
    MaxConnectionsPerChild   0
</IfModule>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

But when my server receives ~8200 concurrent connections, an error is fired and apache not respond anymore:

[notice] caught SIGTERM, shutting down

The server has enough memory left.

Is the configuration ok? Do I have to change anything?

Thanks

You might be running into your systems process limit. Check with ulimit -u and see this question.
