We have set up sentry 8.6.0. Whenever we are running below command, we are getting error
$ supervisorctl status
sentry-cron FATAL Exited too quickly (process log may have details)
sentry-web FATAL Exited too quickly (process log may have details)
sentry-worker FATAL Exited too quickly (process log may have details)
Well, what are in the logs? 
We were getting this errors while giving
$ supervisorctl status
sentry-cron FATAL Exited too quickly (process log may have details)
sentry-web RUNNING pid 1927, uptime 0:25:52
sentry-worker FATAL Exited too quickly (process log may have details)
Checked the sentry config
**$ vim /etc/supervisor/conf.d/sentry.conf **
[program:sentry-worker]
command=/home/sentry/sentry_app/bin/sentry celery worker
[program:sentry-cron]
command=/home/sentry/sentry_app/bin/sentry celery beat
So, changed the sentry config to
**$ vim /etc/supervisor/conf.d/sentry.conf **
[program:sentry-worker]
command=/home/sentry/sentry_app/bin/sentry run worker
[program:sentry-cron]
command=/home/sentry/sentry_app/bin/sentry run cron
and rebooted the system.
$ supervisorctl status
sentry-cron RUNNING pid 1872, uptime 2:32:23
sentry-web RUNNING pid 1867, uptime 2:32:23
sentry-worker RUNNING pid 1874, uptime 2:32:23
fwiw this change has been deprecated for many months and was documented through changelogs.
