FastCGI错误:(104)连接重置由同行,不完整的标题和其他

我正在使用cPhalcon编写Web应用程序。 我testing的机器是严格的开发,所以没有任何来自外部的stream量。 问题是,当我试图做

$this->flashSession->getMessages(); 

我总是这样的错误:

 [Fri Jul 04 00:49:44 2014] [error] [client xxxxxx] (104)Connection reset by peer: FastCGI: comm with server "/var/www/.../cgi-bin/php5-fcgi-*-80-domain.com" aborted: read failed [Fri Jul 04 00:49:44 2014] [error] [client xxxxxx] FastCGI: incomplete headers (0 bytes) received from server "/var/www/.../cgi-bin/php5-fcgi-*-80-domain.com" [Fri Jul 04 00:49:44 2014] [error] [client xxxxxx] client denied by server configuration: /var/www/domain.com/web/error/500.html 

在服务器上我使用ISPConfig。 我一直在读这个,我已经在vhostconfigurationFastCgiExternalServer -idle-timeout 3600

什么可能是错的?
