I have VPS 8cpu, 16gb ram. php-fpm+Redis+po full page cache
Sometimes multiple php processes appearing and not finishing. Eating cpu each one of them. Almost %100 cpu usage. Memory is below %10
I activated maintanance mode. maintenance.flag is active. Web site is not online.
I restarted php-fpm
Processes stopped, after couple of minutes started again and still continue.
When I activate magento Server is not stucked, I can reach whm and ssh but magento is sooo slow.
How can I find what is working? Or which script is working?
