Nginx failed with php5-fpm for new php frameworks

[AARYAN ADITYA]

Hi Team,

Today i got a very strange error . In my server i have deployed 3 php web application . which are bult using yii ,laravel php and wordpress frameworks . but one my website is loading very slow which is built with laravel. when i see error log .. for every one minute 2 errors are logged .. same error repeated for whole day. i contacted larvel they confirmed that its problem with nginx .. its not perfectly compiling with php5-fpm . The thing is that when i check load testing .. its noot even accepting 50 requests .

Here is the error info

Environment:

Server Software: nginx/1.5.6
operating system: Ubuntu 13.04 (Linux 3.8.0-26-generic)
Fastcgi: php-fpm
php version: PHP 5.5.6-1+debphp.org~raring+2 (cli) (built: Nov 21 2013 14:39:09)
mysql 5.5
laravel : 4.0

wt@localhost:~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Here the strange thing is i am not getting any errors for remaining two websites . if this error raised really due to permission problem .. other websites also should report the same error . but they are not reporting anything ...

i even tried this also

sudo chown www-data.www-data /var/lib/nginx

but after this also same error repeated for same website

If you are not sure you've found a bug, please ask for help via ​mailing list instead.

(Errors logged suggest you have problem with permissions on /var/lib/nginx/fastcgi/*. Note that checking permissions on the /var/lib/nginx/fastcgi alone is not enough, you have to check both higher level directories and the directory contents.)
