Virtual machine exited abruptly

[dar]

My app was processing messages from Kafka and suddenly it stopped and in the middle of processing. I don’t see any resource issue either. Is this based on auto shutdown because no HTTP request is coming in during this ? How to handle it from not terminating while processing ?

See this reply

Machine downscaled even if a process is running

afaik the autoscaler(proxy) works based on network traffic, and long running processes inside your vms are invisible to the autoscaler, which is why your vm is being shutdown. Here’s what I think you can do. You can disable scale-to-zero and update your application to shut down the VM when it’s done running. Then, you can delegate the starting of your application to the autoscaler, by setting the auto_start_machines = true You can find more on autostart and autostop here

so If I ping my app for every message it process it should keep the app alive ? is there a private address for the app that I can call to avoid going public route or do I need to call my hostname to hit fly proxy ?

The link I shared should work for your usecase.

Yeah, they’re called flycast addresses. They’re private addresses that go through the proxy. See Private Networking · Fly Docs
