help pls with RuntimeError: no running event loop

[danial29rus]

Hello everyone!

Please tell me if anyone has encountered a problem in granian
with the error RuntimeError: no running event loop

I launch the application like this
command: >-
sh -c "
granian --interface asgi app.main:app --access-log --workers=12 --host=0.0.0.0 --port=8021 --backlog=16192
"
What could be the problem?

I'm switching back to uvicorn and I don't encounter this error

@danial29rus you have something in your application bootstrap that initialise the event loop, but that's not supported in Granian. You should use asyncio.get_event_loop() in case you need the running loop.

But I encounter this error only when there is a heavy load, during normal times there is no error

Then you should provide more details, like:

• a stacktrace
• OS, Python version, event-loop used
• runtime (docker, k8s, host)
• description of the type of workload (including but not limited to the framework/libs used)
