Upstream description:

Using SuSE MicroOS with a bunch of macvlan-using containers, I see netvark-dhcp-proxy hanging every few days. From journalctl:

netavark[14606]: thread 'tokio-runtime-worker' panicked at 'failed to spawn thread: Os { code: 11, kind: WouldBlock, message: "Resource temporarily unavailable" }', /home/abuild/rpmbuild/BUILD/rustc-1.71.1-src/library/std/src/thread/mod.rs:686:29

Even with RUST_BACKTRACE=1 set, it doesn't give a backtrace. Last time this happened, ps reported over 4000 threads for the PID.
