supervisord unknown error making dispatchers for : ENOENT

Question

The supervisord config as below, myserver is golang executable put into dir /usr/tci/bin. And it indeed existed in the dir, why I still get the ENOENT error? ENOENT means can't find the entry.

[supervisord]
nodaemon=true
loglevel=debug

[program:myserver]
command=/usr/tci/bin/myserver
autostart=true
autorestart=true

Error msg:

2018-03-05 08:39:00,230 INFO spawnerr: unknown error making dispatchers for 'myserver': ENOENT

Make sure the directory that holds your log files exists.

Supervisor was running when I removed its log directory /var/log/supervisor. I first noticed the issue when I tried to restart a process which resulted in an unknown error making dispatchers for ENOENT error

I readded the directory by running: mkdir /var/log/supervisor

This fixed the issue and allowed me to restart my process sucessfully. I would also imagine a

sudo service supervisor restart

would fix it since it might generate the missing directory.

Make sure you have logfile set then restart the server: sudo service supervisor restart

My logging config: loglevel=debug logfile =/var/log/supervisor/myserver.log `
