WARNING: [pool instahd.info] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 32 children, there are 27 idle, and 240 total children

My current PHP-FPM pool setting is following

pm = dynamic
pm.start_servers = 35
pm.min_spare_servers = 30
pm.max_spare_servers = 70
pm.max_children = 2500
pm.max_requests = 2500
