DoublyBufferedData的[基本工作原理](https://github.com/apache/incubator-brpc/blob/master/docs/cn/lalb.md#doublybuffereddata)是为每个线程都设置一把锁，ScopedPtr用RAII的方式管理了这个per thread的锁，你的例子里，在临界区中发起了rpc。brpc中，锁内rpc属于未定义行为（大概率会造成死锁）。 建议把std::unique_ptr<brpc::Channel> 换成 std::shared_ptr<brpc::Channel>： ``` std::shared_ptr<brpc::Channel> chan; { butil::DoublyBufferedData<std::unique_ptr<brpc::Channel>>::ScopedPtr c; channel.Read(&c); chan = c; } chan->CallMethod(...); ``` -- This is an automated message from the Apache Git Service.
