mod_fcgid: read data timeout in 40 seconds

for PHP/Perl Processes which are long running without any output, just add to the VHOST Apache configuration: 

<ifmodule mod_fcgid.c>
      IdleTimeout 3600
      ProcessLifeTime 7200
      MaxProcessCount 1000
      DefaultMinClassProcessCount 3
      DefaultMaxClassProcessCount 100
      IPCConnectTimeout 8
      IPCCommTimeout 360
      BusyTimeout 300
</ifmodule>

The parameters has to be set per vhost, otherwise the defaults apply.
