Issue
I noticed dynos for a Private Space app keep restarting without reaching the up state. How can I get them up again?
Resolution
There are some reasons the platform cannot restart dynos by itself. First, please try restarting the dyno, e.g., web.1 for an app sushi, on the same dyno server with the Heroku CLI command:
heroku ps:restart web.1 -a sushi
Restarting the dyno on the same server should resolve the problem on the dyno container. If the situation does't improve after a few minutes, the cause of the problem may be on the dyno serever. Please try restarting the dyno onto a newly provisioned dyno server with the Heroku CLI command like the below. It may take a few minutes for the dyno server to be ready.
heroku ps:stop web.1 -a sushi
If this doesn't improve the sitaution, the service that manages the state of components for the Private Space, including the dynos, might be being overwhelmed. Please scale the dynos down to zero with the Heroku CLI command:
heroku ps:scale web=0 -a sushi
wait for a few minutes, and scale the dynos back up to the original number with, e.g.,:
heroku ps:scale web=2 -a sushi
If this doesn't improve the situation, there may be stale states stored for the Private Space. Please contact Heroku support from https://help.heroku.com/ and let us know the timestamp and the UTC offset from when you noticed the problem, name(s) of the app(s) and the dyno(s) that exhibits the problem.
