Supervisord: Docker : INFO reaped unknown pid

You use supervisord to manage your docker startup services, then you see a bunch of errors like this

2023-02-15 13:15:11,983 INFO reaped unknown pid 475
2023-02-15 13:15:15,452 INFO reaped unknown pid 486
2023-02-15 13:15:15,823 INFO reaped unknown pid 493
2023-02-15 13:16:02,366 INFO reaped unknown pid 506
2023-02-15 13:17:02,045 INFO reaped unknown pid 524
2023-02-15 13:18:01,205 INFO reaped unknown pid 53

The fix is to update your /etc/supervisord.conf , add or change the “loglevel=error”

[supervisord]
nodaemon=true
logfile=/tmp/supervisord.log
pidfile=/var/run/supervisord.pid
user=root
loglevel=error
