Description:
------------
Having set the pool to static with max_children to 5 I would expect the metric "active processes" to be 5 or below. Sending 10 concurrent requests will have "active processes" report more than 5 (e.g. 10, 12, 25, ...).

Is this valid behaviour?


Pool configuration:

# grep -v ";" /usr/local/etc/php-fpm.d/www.conf | grep -Ev "^$"
[www]
user = www-data
group = www-data
listen = 127.0.0.1:9000
pm = static
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.process_idle_timeout = 10s
pm.max_requests = 500
pm.status_path = /status
ping.response = pong
slowlog = log/$pool.log.slow
request_slowlog_timeout = 0
request_terminate_timeout = 0

Expected result:
----------------
Metric "active processes" from /status should be below 5.

Actual result:
--------------
Metric "active processes" from /status is above 5.
