Exited too quickly (process log may have details)-配置问题

在配置supervisor的时候，提示Exited too quickly (process log may have details)，这个时候一脸懵逼，啥回事，执行太快了？？？

而后仔细看了program块的配置，发现因为本身是在测试，运行的命令是sleep 1,而startsecs设置为3，supervisor认为程序执行太快致使出错，把命令改为sleep 4就能够了

[program:demo]
command=sleep 1
directory=/
autostart=true
startsecs=3
autorestart=true
startretries=3
; user=root
priority=999
redirect_stderr=true
stdout_logfile_maxbytes=20MB
stdout_logfile_backups = 20
stdout_logfile=/tmp/supervisord/demo.log
stopasgroup=false
killasgroup=false
