So far stable I'm waiting for the first crash.

2 crashes during the night and all pages never loading in the morning until I restart php-fpm

Almost stable now with these settings:

pm = dynamic
pm.max_children = 200
pm.start_servers = 10
pm.min_spare_servers = 10
pm.max_spare_servers = 20
pm.max_requests = 500

pm.process_idle_timeout = 10s

ps --no-headers -o "rss,cmd" -C php-fpm | awk '{ sum+=$1 } END { printf ("%d%s\n", sum/NR/1024,"M") }'

Shows just 14M per each php-fpm process - so 200 children is just 2,8 GB RAM

Allright - full stable
