openclaw - 💡(How to fix) Fix CPU 100% stuck in ArrayMap/OrderedHashSet::Rehash — gateway infinite loop

Environment

• OS: macOS 12.7.6 (Intel)
• Node.js: v24.14.0
• OpenClaw: 2026.5.22
• Install: npm global

Problem

The openclaw gateway process consumes 100%+ CPU within seconds of starting, even with ALL channels and plugins disabled.

Evidence

1. CPU Sample (macOS sample command)

The process is stuck in a tight loop:

Builtins_ArrayMap
  -> OrderedHashSet::Rehash
    -> Object::GetSimpleHash
      -> SetPrototypeAdd

656 out of 1387 samples in Builtins_ArrayMap — an infinite or extremely long-running hash table operation.

2. All channels AND plugins disabled — CPU still 126%

"channels": { "feishu": {"enabled": false}, "openclaw-weixin": {"enabled": false}, "telegram": {"enabled": false} },
"plugins": { "entries": { "all": {"enabled": false} } }

CPU remains 126.6%. The issue is in the core gateway code, not in any channel or plugin.

3. API connectivity is fine

• curl https://api.apifree.ai/agent/v1/models → 200 OK in 1.6s
• curl https://open.feishu.cn/... → 200 OK in 0.08s
• No proxy interference (system proxy disabled)

4. Startup log shows normal start then spike

gateway: ready
heartbeat: started
startup model warmup timed out after 5000ms; continuing without waiting
cron: started

After this, CPU goes to 100% and stays there indefinitely.

Reproduction Steps

1. npm install -g [email protected]
2. openclaw gateway --port 18789
3. Wait 15 seconds
4. ps aux | grep openclaw — CPU 100%+

Workaround

pkill -9 -f "openclaw.*gateway"
launchctl bootout gui/$(id -u)/ai.openclaw.gateway

Suspected Cause

V8 engine stuck in an infinite ArrayMap + OrderedHashSet::Rehash loop, likely in the dedup system, session management, or cron startup code. The hash table rehashing pattern suggests a data structure that keeps growing or is rebuilt repeatedly in a tight loop.
