Description

I occasionally hit a hang where OpenCode stays in running / thinking forever.

When it happens, no new tool output or assistant text appears, but the session does not return to idle. If I press Esc twice to interrupt, it usually recovers, and retrying the same prompt often works.

This is low-frequency (intermittent), so I don't have a deterministic repro yet, but it keeps happening in normal usage.

It might be related to stream/network interruptions, but I can't confirm.

Possibly related: #11865 #12234 #13841 #14676.

Plugins

None (no custom plugins enabled in this workspace).

OpenCode version

v1.2.x (I can provide exact patch version if needed).

Steps to reproduce

  1. Start a normal coding session.
  2. Ask for tasks that use multiple tool calls (for example read/glob/grep/bash/task).
  3. Continue working for a while.
  4. Occasionally, the session stops producing progress but still shows as running.
  5. Wait several minutes (still stuck), then press Esc / Esc to interrupt.
  6. Retry the same prompt; it often succeeds.

Screenshot and/or share link

No share link yet. I can attach logs on the next occurrence.

Operating System

Linux

Terminal

Terminal emulator on Linux (can share exact terminal app if needed).
