   Thanks for the report! To work out what's going on, could you share a few more details?

   1. Which client were you using: the desktop app, the web app, or the TUI? Also, which OS are you on?
   2. How the background process started: for example, the agent ran a shell command with background: true, or a background subagent. A rough example of the command would help.
   3. Is the process actually still running? Check with ps, Activity Monitor or Task Manager. Or has the process already exited, and only the item in the UI still shows as running with an x that does nothing?
   4. When it got stuck, if you know: for example, right away, or after the session had been idle for a while (about an hour or more).

   You can reply here with the details or edit the issue. If you edit it, please also leave a comment saying you've updated it, so we know when you're done.

   These existing issues look related, ordered from most to least likely:

   • jobs: background shell stuck running after process death; stale UI item cannot be cleared #56804: a background shell stays "running" in the UI after its process is gone, and "Kill shell command" does nothing until opencode service restart. If your processes are no longer alive, this is probably the same problem.
   • v2: shell: no way to stop a running background command #36424: there's no way for the agent to stop a running background command by its shell ID. This matches the "agent can't see them" part.
   • [Bug] Location inactivity eviction SIGTERMs live background shells after 60 minutes #51828: background shells get killed when a location is evicted after 60 minutes of inactivity, which can leave stale items behind.
   • server: PID 1 does not reap orphaned grandchildren, leaving zombies and shells stuck "running" #53564: zombie (<defunct>) processes that are never reaped when opencode serve runs as PID 1 in a container, leaving shells stuck "running".

   We haven't heard back, so I'm closing this for now. Without knowing which client and OS you were on, or whether the background processes were still running, we couldn't reproduce it or tell which known problem it is.

   If you only see a stale "running" item that the x can't clear, please follow #56804. For the agent not being able to see or stop background commands, follow #36424.

   If it's something different, for example the processes really do keep running after you kill them, reply here with the details from the earlier comment and we can reopen this. Thanks for reporting it!
