[BUG] Hermes Agent TUI hard freeze during MCP server reload (VPS/SSH environment
On April 20th, someone working in a VPS environment over SSH filed a bug report describing a specific failure in Hermes Agent's terminal user interface: a hard freeze triggered during MCP server reload. The details matter here, because this isn't a crash with a stack trace you can hand to a developer. It isn't an error message with a line number. It's nothing. The process stays alive, memory occupied, no output, no response to input, Ctrl+C returning the same silence as everything else. The only way out is killing the terminal session entirely and starting cold. Since that report landed, no additional signals have joined it. No developer acknowledgment, no reproduction from a second user, no fix branch, no "yeah, we know." Just the one account, sitting there, unanswered.
If confirmed, here is what this means. The freeze-without-exit pattern is one of the more disruptive failure modes a developer-facing tool can produce, specifically because it offers no feedback loop. A crash teaches you something. A freeze teaches you to distrust the environment. For anyone running Hermes Agent in remote infrastructure — VPS deployments, SSH-dependent workflows, automated pipelines where a human isn't watching a terminal — this becomes a reliability problem with real operational weight. MCP server reloads aren't edge cases; they're a routine part of managing a live agent configuration. If the reload path is capable of locking the entire TUI, then any workflow that touches that path carries latency risk at minimum, and silent failure risk at worst. The SSH context compounds this: kill the session, lose the state, restart from scratch, wonder what the agent was doing when it froze.
Watch for a second reproduction report from a different environment, or any response from the Hermes Agent maintainers acknowledging the reload path as a known issue — either would sharpen this picture considerably.
