Visited web application from browser and got cant be reached 504 message last night.
On checking the clients server, I was able to see that the timeout error from the web server log:
The timeout specified has expired: [client xxxxxxxx] AH01075: Error dispatching request to : (polling)
I advised client that this was due to them not having configured the PHP FPM values.
Bascially due to the use of the dynamic process manager FPM Config. And that furthermore they should try using Ondemand setting. This relates to the PHP FPM values. And see how that goes.
The site in question is loading pretty fine from our end. But am wondering if this is the best advice. I.e. changing from dynamic to on-demand for a vps 8gb ram, 2 core, 180sd. Any recommendations. Which is best?
Clients is running a wordpress app. High traffic site.
The web application stack is NGINX + Apache2 Hybrid (I can use .htaccess) let me know what else you need to know.
