Tips and tricks to track memory leaks in realtime inside an AsyncIO daemon ?

[Ludovic Gasc]

Hi,

We have now an AsyncIO daemon with memory leaks.

To track this, I'm thinking to use this:

https://pythonhosted.org/Pympler/muppy.html

and objgraph.

But, because it's a live daemon and not a script, instead to implement an HTTP endpoint to launch the memory snapshot locally, I'm thinking to use epdb:
https://github.com/sassoftware/epdb

To have directly a Python console to explore interactively inside the process to have a more flexible way to debug.

I did a quick'n'dirty lab', it seems to work more or less to run epdb inside a thread executor, but before to continue on this idea, I'm interested in how you track your memory leaks inside your AsyncIO daemons ?

Thanks for your feedbacks.

I've done something similar but using aioconsole instead of epdb.
