PHP-FPM
The Instance went down again. Instead of rushing to get the instance back up I check some logs and it appears that when I increased the values I did not increase the pm.max_spare_servers. I allowed more to be generated but did not allow them to exist π. Which of course took php-fpm down.
I increased pm.max_spare_server so hopefully this time I have enough to handle the load. As you can see in the screenshot below as soon as more spare servers were added that brought it above 100, the whole service shutdown bringing the site down.
The setting still may need massaging. Time will show.
