In the logs php7.2-fpm.log periodically POPs up error:
[pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 16 children, there are 0 idle, and 216 total children
Website with no longer boot, have to restart the server.

Settings www.conf have tried many times to change, at the moment are:
pm = dynamic
pm.max_children = 5000
pm.start_servers = 12
pm.min_spare_servers = 10
pm.max_spare_servers = 32
pm.max_requests = 10000
What are the settings to curb this error?
