"Our supplier asks that you double the number of php child processes for this fpm pool"

"Are you aware, that that would lead to about 100% of memory overcommit, taken the current limit of 128MB/child, and that if a lot of them started at once, the system would probably go for OOM-Kill, which would most probably kill your database, that still runs on 100% MyISAM tables that do not support transactions, and you'd have to kiss your data integrity goodbye, right?"

"Uh... Nevermind then"

I get that some people are not IT-versed, but really... Hire someone who knows what they are doing and doesn't live 20 years in the past, god damn it!
