openclaw channels capabilities --channel discord hangs and spawns an openclaw-channels process pegged at ~99% CPU.

This happened during a Discord ingress diagnostic on a production gateway. The command did not return promptly, emitted plugin runtime dependency staging output, and left child processes consuming CPU until manually killed.

Error Message

The command should return Discord capability/intents information quickly, or fail with a bounded timeout and actionable error.

Root Cause

openclaw channels capabilities --channel discord hangs and spawns an openclaw-channels process pegged at ~99% CPU.

This happened during a Discord ingress diagnostic on a production gateway. The command did not return promptly, emitted plugin runtime dependency staging output, and left child processes consuming CPU until manually killed.

Code Example

openclaw channels capabilities --channel discord

---

openclaw
openclaw-channels 99% CPU

---

kill -9 <openclaw-channels-pid>

Summary

openclaw channels capabilities --channel discord hangs and spawns an openclaw-channels process pegged at ~99% CPU.

This happened during a Discord ingress diagnostic on a production gateway. The command did not return promptly, emitted plugin runtime dependency staging output, and left child processes consuming CPU until manually killed.

Environment

  • OpenClaw: 2026.4.29
  • Node: v22.22.2
  • OS: Ubuntu / Linux 6.8.0-110-generic
  • Gateway: systemd user service, running on 127.0.0.1:18789
  • Channels configured: Discord + Telegram
  • Discord status: enabled, configured, running, connected

Repro

openclaw channels capabilities --channel discord

Observed process state:

openclaw
openclaw-channels 99% CPU

The command did not complete in the diagnostic window and had to be terminated:

kill -9 <openclaw-channels-pid>

Expected behavior

The command should return Discord capability/intents information quickly, or fail with a bounded timeout and actionable error.

Actual behavior

The command hangs and leaves CPU-bound openclaw-channels child processes. This can materially worsen gateway latency if left running during live Discord/Telegram traffic.

Additional context

During the same diagnostic, direct Discord API checks showed the bot/app data was accessible and fast, so this does not look like generic network failure:

bot_user id=1499306362507886612 username=Ninja Butler
application flags included GATEWAY_MESSAGE_CONTENT_LIMITED
channels list returned the target guild channels successfully

This seems specific to the channels capabilities path, possibly plugin/runtime capability discovery re-entering the same heavy plugin loader path observed in issue #77029.

extent analysis

TL;DR

The issue can be mitigated by investigating and optimizing the plugin/runtime capability discovery process in the openclaw-channels command.

Guidance

  • Investigate the plugin loader path to identify potential re-entrancy issues, as hinted by the similarity to issue #77029.
  • Verify the Discord API checks to ensure the bot/app data is accessible and fast, as shown in the additional context.
  • Check the openclaw-channels process to see if it's stuck in an infinite loop or waiting for a timeout, and consider implementing a bounded timeout for the command.
  • Review the system resources and CPU usage to determine if the issue is specific to the openclaw-channels process or a broader system issue.

Example

No code snippet is provided as the issue does not explicitly mention a specific code block that needs modification.

Notes

The issue seems specific to the channels capabilities path and may be related to plugin/runtime capability discovery. Further investigation is needed to determine the root cause and implement a fix.

Recommendation

Apply a workaround by implementing a timeout for the openclaw channels capabilities --channel discord command to prevent it from hanging indefinitely and consuming CPU resources. This can help mitigate the issue until a permanent fix is found.
