    Question Apache & PHP-FPM memory usage spike and no CPU usage

    but where is the bottleneck? I did try increasing the processes from 10 to 20, then 20 to 50, then 50 to 80 then 80 to 100 (over a period of days), yet still, when the Apache and PHP memory went above circa 954MiB the same symptoms occured.

    Question Apache & PHP-FPM memory usage spike and no CPU usage

    Hi. Thanks for your reply. I've been looking at the access logs and can't see any major spikes. I did see AhrefsBot was crawling links which i've since prevented in the robots.txt but i'm not sure if this could have been related. I also forgot to mention the website uses Wordpress 5.8 but also...

    Question Apache & PHP-FPM memory usage spike and no CPU usage

    Thanks for the reply. Don't have /var/log/messages. Can't see anything worthwhile in the httpd logs other than the 504 reponses. We are using nginx as a proxy and are seeing lots of these entries in the proxy logs: 2021/08/30 11:35:13 [error] 278301#0: *6391166 upstream timed out (110...

    Hi, I'm struggling to narrow down some really high spikes in apache and php-fpm memory usage, which coinsides with a complete drop in apache and php-fpm cpu usage. See attached images. This is causing a gateway timeout message on the website during these memory spikes. I've gone through the...
