Performance Tuning und Ermittlug Mysql PHP Apache

[MatzeAug]

Das Problem konnte mehr oder minder gelöst werden.
Zumindest trat das Problem seit folgenden Änderungen der Apache Konfiguration nicht mehr auf.

Konfiguration alt:
<IfModule prefork.c>
 # number of server processes to start
 StartServers         5
 # minimum number of server processes which are kept spare
 MinSpareServers      10
 # maximum number of server processes which are kept spare
 MaxSpareServers    20
 # highest possible MaxClients setting for the lifetime of the Apache process.
 ServerLimit        25
 # maximum number of server processes allowed to start
 MaxClients         25
 # maximum number of requests a server process serves
 MaxRequestsPerChild  0
</IfModule>

KeepAlive On
MaxKeepAliveRequests 0
KeepAliveTimeout 15

Konfiguration neu:
<IfModule prefork.c>
