We are experiencing some memory issues and can’t identify what is going on. It doesn’t happen everytime you try to load a page but does happen very frequently (like every other time). The error we are seeing in /srv/www/www.woodgrain.com/logs/error.log is:
FastCGI sent in stderr: “PHP message: PHP Fatal error: Allowed memory size of 100663296 bytes exhausted (tried to allocate 20480 bytes) in /srv/www/www.woodgrain.com/releases/20190423055327/web/wp/wp-includes/meta.php on line 846” while reading response header from upstream, client: 188.8.131.52, server: www.woodgrain.com, request: “GET /autodiscover/autodiscover.xml HTTP/1.1”, upstream: “fastcgi://unix:/var/run/php-fpm-wordpress.sock:”, host: “www.woodgrain.com”
We have tried adjusting the FastCGI Buffer size to 8 32k and that hasn’t made a difference.
