Today I deploy my app many times, deployment succeed, but after few minutes, monitor print the following information. I try to change region, but dosen’t work, What should I do? ```auto 2023-04-18T06:36:17.032 app[6e82e25c206987] waw [info] Sending signal SIGINT to main child process w/ PID 513 2023-04-18T06:36:17.040 proxy [6e82e25c206987] waw [info] Downscaling app aabb123 in region waw.

Same issue here. It seems apps are scaling to zero, which means they stop if they don’t receive traffic for a few minutes. I don’t want this, is there any way to disable it? I’ve already tried `fly scale count 1` but it seems to have no effect. ---

You can set `auto_stop_machines = false` under the `[http_service]` section of `fly.toml` to prevent `fly-proxy` from stopping the machines in case of inactivity. ---

@pavel what is considered to be inactivity? ---

In this particular case, since there is only one machine for the app - `fly-proxy` will consider downscaling if there are no requests to the app. ---

Is this parameter described anywhere? I haven’t found any mention of `auto_stop_machines` in the [Fly.io: A New Public Cloud · Fly Docs](http://fly.io/docs) What is the lag between last request and shutdown? How will it behave if there is more than one machine for the app? In more than one region? ---

In more than one region? The algorithm is not set in stone and might change in the future, but for now it evaluates app’s load every three minutes. If you have more than one app instance in a region the downscaler checks app’s load against configured `soft_limit` and considers downscaling the app only if you have two or more app instances with load below `soft_limit` in this region. This happens independently in each region. ---
