Sphinx/Searchd: Supervisord autorestart not working

Question

We are running sphinx through supervisord inside docker. We are trying to enable autorestart, but it does work. We are trying to verify this by manually killing the searchd process.

Below is the configuration

[program:sphinx]
command=searchd --pidfile --config "config/sphinx.conf"
autostart=true
autorestart=unexpected
startsecs=5
startretries=3
exitcodes=0

We also attempted other configuration

program:sphinx] 
command= rake ts:stop 
command= rake ts:configure
command= rake ts:start 
autostart=true 
exitcodes=0,2
autorestart=unexpected

Are we missing something?
