Php 督导员superlance memmon不工作

supervisord.conf

[eventlistener:memmon]
command=/usr/local/bin/memmon -p system_message_dispatch=35MB
events=TICK_60

[program:system_message_dispatch]
command                 = php /mnt/www/project/artisan queue:work --queue=system_message_dispatch --sleep=3 --tries=3 --daemon
process_name            = %(program_name)s_%(process_num)02d
numprocs                = 6
autostart               = true
autorestart             = true
stdout_logfile          = /tmp/supervisor_system_message_dispatch.log
stdout_logfile_maxbytes = 10MB
stderr_logfile          = /tmp/supervisor_system_message_dispatch.err.log
stderr_logfile_maxbytes = 10MB

我的问题是： 当程序system_message_dispatch的RSS超过35MB时，此程序不会重新启动，但memmon有响应

supervisor> tail memmon
