Can "active processes" be larger than "max_children" for PHP-FPM : <p>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, ...).</p>

<p>Is this valid behaviour?</p>

<p>Pool configuration:</p>

<pre><code># 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
</code></pre>

<p><strong>Expected result:</strong>
Metric "active processes" from /status should be below 5.</p>

<p><strong>Actual result:</strong>
Metric "active processes" from /status is above 5.</p>
