Bug #76003 [NEW]: FPM /status reports wrong number of active processes

From: enrico dot stahn at gmail dot com Operating system: Alpine PHP version: 7.1.14 Package: FPM related Bug Type: Bug Bug description:FPM /status reports wrong number of active processes 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. -- Edit bug report at https://bugs.php.net/bug.php?id=76003&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76003&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76003&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76003&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76003&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76003&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76003&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76003&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76003&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76003&r=support Expected behavior: https://bugs.php.net/fix.php?id=76003&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76003&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76003&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76003&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76003&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76003&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76003&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76003&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76003&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76003&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76003&r=mysqlcfg
