I have a website that receives a lot of traffic load, and when php is not able to handle all requests the web starts to slow down, even at certain times causes an error 502 nginx, I have this setting in the php file, I have been modifying but I can not find the problem. the server has 30 gb of ram and 8 cpus, running the htop command I do not see that the server is saturated.
some one can help me to fixit.
Regards
