Bug Description

2026-03-30T15:06:07.905+08:00 [openclaw] Uncaught exception: Error: Unable to update lock within the stale threshold
    at /root/.openclaw/plugins/memory-lancedb-pro/node_modules/proper-lockfile/lib/lockfile.js:136:25
    at callback (/root/.openclaw/plugins/memory-lancedb-pro/node_modules/graceful-fs/polyfills.js:306:20)
    at FSReqCallback.oncomplete (node:fs:197:5)
    at FSReqCallback.callbackTrampoline (node:internal/async_hooks:130:17)

这个错误会导致openclaw gateway进程退出

Steps to Reproduce

和多agent每个agent有各自的workspace有关系吗？

这是一个 proper-lockfile 并发问题——当多个进程同时尝试访问 LanceDB 数据库时就会发生这种情况（例如，多个代理或在后台任务运行时重启网关）。

需要检查以下几点：

1. 您是否运行了多个指向同一 LanceDB 路径的 OpenClaw 实例？
2. 您最近是否在内存操作进行期间重启过网关？
3. 检查 LanceDB 目录中是否存在过期的 .lock 文件： ls ~/.openclaw/memory/lancedb-pro/*.lock

作为一种变通方法，您可以停止 OpenClaw，删除任何过时的锁定文件，然后重新启动。

1、只有一个Openclaw实例，但是有多个agent，每个agent有自己的工作空间，LanceDB路径没指定设置
2、有异常重启过几次，不确定最开始的重启是不是在刚好内存操作期间
3、现在只看到有一个 .memory-write.lock
4、我之前是设置的 "autoRecall": false，后面设置"autoRecall": true 后出现这个错误，不确定有没有关系；现在我又改回了 "autoRecall": false，目前没有再出现这个错

要怎么为每个agent设置 dbPath 呢？文档看起来dbPath似乎没办法为每个agent单独配置

PR 準備好了

PR #517 修復了這個問題，包含兩個核心變更：

1. stale: 10s → 60s + retries max wait: 3s → 151s
2. ECOMPROMISED graceful fallback：不等於立刻崩，先等3秒再試一次
