I think, I found a BUG in CGI module.... In CGI soucrce code is this function which read only 10000 bytes from 13100 which my browser sends: 
'read_from_client' => <<'END_OF_FUNC',                                
+                                                        
# Read data from a file handle                                        
+                                                        
sub read_from_client {                                                
+                                                        
my($self, $buff, $len, $offset) = @_;                                 
+                        
local $^W=0;                # prevent a warning      

return $MOD_PERL ? $self->r->read($$buff, $len, $offset) : read(\*STDI
+N, $$buff, $len, $offset);                                           
+                                   
}                                                                     
+

This looks ok, but the function calling looks like, it program some kid: 
if ($meth eq 'POST') {                                                
+                                                  
      $self->read_from_client(\$query_string,$content_length,0)       
+                                                    
            if $content_length > 0;                                   
+                                                      
      # Some people want to have their cake and eat it too!           
+                                                    
      # Uncomment this line to have the contents of the query string  
+                                                    
      # APPENDED to the POST data.                                    
+                                                    
      #$query_string .= (length($query_string) ? '&' : '') . $ENV{'QUE
+RY_STRING'} if defined $ENV{'QUERY_STRING'};        
                                                                      
+                                                
    last METHOD;                                                      
+                                                  
}

This only read ONCE! from stdin and does NOT check how many bytes it read!! :-( So my read function on my kvm machine read only 10000 bytes from 13100 and thats all :-/
