Socket files for mDNS not closed after closing peer_connection?

[deepushajia]

/home/nvidia/.cargo/registry/src/index.crates.io-6f17d22bba15001f/webrtc-mdns-0.6.1/src/conn/mod.rs:75 | Error getting interfaces: Os { code: 24, kind: Uncategorized, message: "Too many open files" }

There seem to be a socket file leak happening,
My code is similar to the one here:
https://github.com/webrtc-rs/webrtc/blob/master/examples/examples/data-channels/data-channels.rs

Just that I am instantiating a tokio runtime async thread for every connection made, I make sure to use the peer_connection.close().await before the thread is closed. It works without issue normally, but when I reach somewhere around 200 connections (always occur at 190-210 range), this error pops up.

Same here.
I use lsof -n -p $pid to monitor the file description and it keep on increasing.
