**Describe the bug (描述bug)**
客户端偶发出现 `[E1008]Reached timeout=15000ms`，从 rpcz
抓到的trace看，服务端很快进行了response，但是不知道什么原因客户端一直没有收到，其中一个trace如下
```

按照
[server_debugging](https://github.com/apache/brpc/blob/master/docs/cn/server_debugging.md)对客户端和服务端进行了排查
* bthread_worker_usage 很低 (但依然尝试增加 brpc_concurrency，没有效果)
* 机器的CPU、IO和网络带宽都没有用满
**To Reproduce (复现方法)**
**Expected behavior (期望行为)**
**Versions (各种版本)**
brpc: 1.3.0
