After last Nginx update couple of days ago, I'm getting the following 504 Gateway Time-out nginx/1.2.7 when I use any of the web forms (oSticket & WordPress) Log 2013/02/20 23:38:13 [error] 14032#0: *15756 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 192.168.1.122, server: mydomain.com, request: "POST /contact/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9024", host: "mydomain.com", referrer: "http://mydomain.com/contact/" Did anything change within nginx, anyone else has this issue, any idea how to fix. Thanks! Here's my existing nginx directive: Code: location / { try_files $uri $uri/ /index.php?$args; } # Add trailing slash to */wp-admin requests. rewrite /wp-admin$ $scheme://$host$uri/ permanent; location ~* \.(jpg|jpeg|png|gif|css|js|ico)$ { expires max; log_not_found off; } location ~* \.php$ { fastcgi_pass 127.0.0.1:9001; fastcgi_index index.php; fastcgi_split_path_info ^(.+\.php)(.*)$; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_temp_file_write_size 10m; fastcgi_busy_buffers_size 512k; fastcgi_buffer_size 512k; fastcgi_buffers 16 512k; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_intercept_errors on; fastcgi_next_upstream error invalid_header timeout http_500; }
Hi Falko, Thanks for your reply. PHP-FPM pool is running on port 9024, I restarted it. Same problem, anything else I should check?

I just started experience this on a few VM servers. A quick fix that worked was doing a server reboot, but can't be rebooting all the time so gotta find a solution soon. My setup is varnish -> nginx -> php-fpm I'll be looking into it now if I find anything I'll post here.
My problem is no persistant after the reboot it stays good for sometime, its not happening everytime. But I'm testing different configs (even though the setup has been running for the past year without a problem), maybe its a new update thing. Try this on your nginx config for the php-fpm Change From: To:
Webelo Thanks! Unfortunately, that change also didn't help. Since NGINX upgrade to 1.2.7 web forms aren't working and I've been looking to fix this for last two weeks, I don't know if this is NGINX bug or something else. I posted same questions on their forum asked on support chat - still no help! I don't know if it's possible to downgrade NGINX to previous version and how, would that even fix the issue? I will most likely have to re-install my server with Apache because it's widely used where if there's an issue I'm sure there's a solution available faster.
There seems to be a serious problem with your setup, and I doubt it has anything to do with nginx. It seems more like an issue with PHP-FPM. Have you tried to build and use another PHP version?
Yep 502 Gateway Error. I think I went wrong adding the additional php versions via tutorial mid installation. Not sure if performing the tutorial again will fix the socket and problem or not. 2013/07/11 00:36:35 [crit] 26485#0: *27 connect() to unix:/var/lib/php5-fpm/ispconfig.sock failed (2: No such file or directory) while connecting to upstream, client: xx.xx.xx.xx, server: _, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/lib/php5-fpm/ispconfig.sock:", host: "xx.xx.xx.xx:8080"
