Are there max requests settings for Daphne?
alamorre opened this issue · comments
I have this ASGI applicate with Django and Daphne, and I'm using the following command.
daphne -b 0.0.0.0 -p $PORT server.asgi:application
Is there a way to add --max-requests and --max-requests-jitter to actively prevent memory leaks?
Maybe something like:
daphne -b 0.0.0.0 -p $PORT --max-requests 1000 --max-requests-jitter 50 server.asgi:application
Not currently, but it might be a good addition. 🤔
This is ref:
Were you able to investigate why you're seeing a leak there? Also did it stabilise at 4%? (In which case it may be the Python GC rather than a leak per se — for which it'd keep going up.)
It's really a verbatim implementation of the tutorial project in the docs. In production it leaks in the picture below.
That's why i think --max-requests with daphne would be awesome. We can let an image teardown before consuming too many resources.
I created this draft PR #405
Please let me know if this is of interest. I'll polish the code and make some unit tests 👍
hello guys, i'm using gunicorn now, it has an option to choose the class of workers, in my case i use gthreads(green thread), is there an option like this in daphne?
@WellingtonNico No. It wouldn't make much sense. ASGI uses asyncio, with multiple requests handled in the single event loop. You can run multiple instances of Daphne (but you should be a while before you'd need to do that...)
