Snowflake container crashes after a few days

I am running Snowflake on my VPS as a podman container, with the following:

podman run --net host -m=700M -d snowflake-proxy

I have been running this for a few months, and it tends to crash after one to ten days. If I look at the memory usage, I see that it has a tendency to grow. At some point I was monitoring more closely, and pretty clearly it would crash after reaching the limit (at first I had no limit and it would crash my VPS, now I guess it's just stopped by podman when it uses more than 700M).

My guess is that Snowflake does not keep much state, so the memory usage should never grow too much, right? This feels like a memory leak, but I am not sure what I can do to get more data.
