Hi,

i got some problems with a high loaded php site running nginx + php
(without fpm).

i get the following error message from time to time:

162503979 upstream timed out (110: Connection timed out) while reading
response header from upstream,


While this occours, nginx stops delivering php content and drops the
error document.

Heres a part of my nginx conf

user webuser1 nginx;

worker_rlimit_nofile 65000;



#error_log /var/log/nginx/error.log debug;

# Load config files from the /etc/nginx/conf.d directory

}


Any Ideas how i could resolv this?

Thanks!
