mod_fcgid: too much

[help40]

[notice] mod_fcgid: too much /var/www/virtual/xxxxx . net/htdocs/index.php process(current:10, max:10), skip the spawn request

any suggestions ?
which parameters must be tuned ?
also in which file

as example
/etc/apache2/mods-enabled/fcgid_ispcp.conf
or
/etc/apache2/mods-available/fcgid_ispcp.conf

they are identical now

Code:

<IfModule mod_fcgid.c>
  AddHandler fcgid-script .php .php5
  SocketPath /var/lib/apache2/fcgid/sock
  IdleTimeout 600
  IdleScanInterval 120
  BusyTimeout 300
  BusyScanInterval 120
  ErrorScanInterval 3
  ZombieScanInterval 3
  ProcessLifeTime 900
  SpawnScoreUpLimit 10
  SpawnScore 1
  TerminationScore 2
  MaxProcessCount 200
  DefaultMaxClassProcessCount 10
  DefaultMinClassProcessCount 1
  IPCConnectTimeout 900
  IPCCommTimeout 900
  MaxRequestsPerProcess 500
</IfModule>
