# NousResearch/hermes-agent · PTY session reaping blocked by attach/socket errors

- PR #110861: fix(dashboard): roll back a mid-replay attach drop so idle reaping can reclaim the PTY
- PR #110863: fix(pty): make failed websocket attachments reapable

Several fixes address scenarios where erroring or dropped WebSocket attachments leave PTY sessions permanently marked as attached, preventing idle reaping from reclaiming them. The changes cover socket send errors, mid-replay drops, and commit-ordering issues in the attach lifecycle — including a case where \`PtySession.attach()\` commits attached state before the replay write, leaving the PTY permanently unreapable if a client drops during attach.
