The default #[tokio::main] uses num_cpus worker threads. On small node VMs (1-2 vCPU), this gives only 1-2 worker threads. The NAT traversal poll() function does synchronous work (parking_lot locks, DashMap iteration) that blocks its worker thread. With only 1 worker, this freezes the entire runtime — timers stop, keepalives can't fire, and connections die silently. Also removes the !.cargo/config.toml exception from .gitignore so local-only patch overrides stay out of version control. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
