I've just edit my PHP-FPM conf with : [code] <value name="emergency_restart_threshold">30</value> <value name="emergency_restart_interval">0s</value> <value name="process_control_timeout">5s</value> [/code] I hope it will correct my problem :) Posted at Nginx Forum: http://forum.nginx.org/read.php?2,91854,92164#msg-92164
