Edit report at https://bugs.php.net/bug.php?id=71989&edit=1 ID: 71989 Updated by: dsp@php.net Reported by: ivan dot shib at gmail dot com Summary: Unable to call the exec function asynchronously -Status: Open +Status: Not a bug Type: Bug Package: Output Control Operating System: 4.1.19-boot2docker x86_64 Linux PHP Version: 7.0.5 Block user comment: N Private report: N New Comment: This is not an error. You are a creating a child process inside the shell without correctly handling it using waitpid. Therefore the FPM module finds an unknown child and writes this warning. The correct way to do this is using something along the line of: $p = pcntl_fork(); if ($p == 0) { // child process exec('php -f index.php'); } else if ($p > 0) { // parent waitpid($p, $status); } else { // error } Previous Comments: ------------------------------------------------------------------------ [2016-04-08 12:59:46] ivan dot shib at gmail dot com Description: ------------ In the php code run the following command: exec('php -f '.escapeshellarg(ROOT_DIR.'/index.php').' > /dev/null 2>&1 &'); Got the following record in the logs: 2016-04-08T12:55:38.201816261Z [08-Apr-2016 12:55:38] ALERT: oops, unknown child (16) exited with code 0. Please open a bug report (https://bugs.php.net). If we remove ' > /dev/null 2>&1 &' part from code then it works fine but not asynchronously. Please note that in PHP v 7.0.3 the code above worked fine. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71989&edit=1
