The worker just restarts for no reason randomly

Troubleshooting and help
1

I have a python fastapi app hosted on free tier of heroku.
I’m getting the following error in the logs after a few minutes when a background process is running on the API. There’s no error before the following lines. But after these lines the worker just restarts!

[2025-05-03 12:22:25 +0000] [1] [CRITICAL] WORKER TIMEOUT (pid:116) [2025-05-03 12:22:26 +0000] [1] [ERROR] Worker (pid:116) was sent SIGABRT! [2025-05-03 12:22:26 +0000] [136] [INFO] Booting worker with pid: 136 [2025-05-03 12:22:30 +0000] [136] [INFO] Started server process [136]

Hi,

I am not sure to understand. Your service seems to be working fine on Koyeb. Are you sure the error is coming from us?
