# NousResearch/hermes-agent · PTY leaks and WS ping config behind reverse proxy

## Open now

- 1 issue, 2 PRs open on GitHub.
- #96418: Loopback bind disables the WS keepalive ping, leaking a PTY child per dead client behind a reverse proxy
- PR #96423: fix(dashboard): let explicit ws_ping config outrank the loopback gate
- PR #119551: fix(serve): reap attached PTY sessions that stop sending frames

These items address two related issues: PTY child processes leaking when dead clients stop sending frames, and a loopback-bind heuristic that suppresses WebSocket keepalive pings even when explicitly configured, causing problems behind reverse proxies.
