这个 BrokenPipeError 是在 Docker 容器关闭或进程退出时，asyncio 的管道还没完全清理导致的常见“关机噪音”日志。LangBot 及其插件 SDK 目前没有专门捕获或抑制这类异常的逻辑，主要原因是插件关闭流程（先关闭连接再 kill 子进程）有可能和底层 asyncio 还在 flush 数据时产生竞争，导致管道已关闭但还有数据写入，从而抛出 BrokenPipeError。这不会影响实际功能，只是日志上会有报错信息，可以安全忽略。如果想要更干净的日志，可以考虑在关闭管道时用 try/except 包裹，捕获并忽略 BrokenPipeError，但目前官方代码没有这样处理相关实现参考。

To reply, just mention @dosu.
