Here’s the entire stacktrace of when this error happens. How you have ulimit configured compared to my desktop or e.g. I expect there are some subtle differences in This does not happen locally or on our last cloud provider. Current fix is to restart the application every 2 days. I’ve tried to remedy this without success. Time, about 2 days, the application soft locks due to the OS blocking new connections to the Postgres server. I run an application based on FastAPI + SQLAlchemy (Postgres with asyncpg).
