[I] server中brpc::StreamWait卡在了thread::TaskGroup::sched_to (brpc)

[via GitHub]

GreateCode opened a new issue, #2680:
URL: https://github.com/apache/brpc/issues/2680

   **Describe the bug (描述bug)**
   server给client端发送几十个G的数据，期间client挂。
   StreamWait的due_time设置的是100ms（是错的，应该是时间点），但也不应该卡住吧。
   client挂和StreamWait卡住先后顺序不确定。
   栈信息如图，请大佬帮忙看看是什么原因。
   
   `
   while(1) {
        int ec = brpc::StreamWrite(xxxx);
        if (ec == EINVAL) { return; }
   
        if (ec == EAGAIN) {
             auto ret = brpc::StreamWait(stream_id, &due_time);
             if (ret == EINVAL) { return; }
        }
   }
   `
