Unknown error code in heroku "One or more of these arguments were missing"

Clarification of the question:

A python app suddenly fails to start on Heroku. There were no changes to the app, but a previously unseen error prevents the app from starting:

One or more of these arguments were missing: uid, gid, gateway, somaxconn, event_fd, out_fd

Since no changes were deployed and restarts don't help it's safe to assume that something changed on Heroku side.

Original post:

My application crashed and I am experiencing problems restarting it. I am getting the same error code every time: One or more of these arguments were missing: uid, gid, gateway, somaxconn, event_fd, out_fd. I do not understand the meaning of this error code along with its origin. Can you please help?

I tried to restart and redeploy the application.
