about ServerLimit and ThreadLimit

[Tseveendorj Ochirlantuu <tseveendorj@xxxxxxxxx>]

Hello,

On the documentation of Apache2.2 

ServerLimit is a hard limit on the number of active child processes, and must be greater than or equal to the MaxClients directive divided by the ThreadsPerChild directive. ThreadLimit is a hard limit of the number of server threads, and must be greater than or equal to the ThreadsPerChild directive.

I did like above on worker MPM but server reached Max connection when 256th connection come.

<IfModule mpm_worker_module>

    StartServers               5

    MaxClients              350

    MinSpareThreads       25

    MaxSpareThreads      75

    ThreadsPerChild         25

    MaxRequestsPerChild   0

    ServerLimit               40

    ThreadLimit              40

</IfModule>

Is there something wrong in my configuration ?

Regards,

Tseveen.
