hi, guys. I have a big problem, it torture me two days. centos 4.7, nginx 0.8.54, php 5.2.14. There’s a page, it’s has four frames each include a php file. 502 bad gateway occured when I use chrome open it. But seldom happened when I use IE. because IE load four php filese sequenced, but chrome paralleled load the four php files. I test a single php file with LoadRunner, no 502 happened. ``` It's confused me. thanks a lot. ``` Posted at Nginx Forum: > **[nginx/0.8.54 502 bad gateway,very strange](https://forum.nginx.org/read.php?2,213624,213624#msg-213624)** > > hi, guys.

I have solved this problem. just change fastcgi address from unix sock to tcp . good luck to us. perhaps it’s a bug on this version.
