binarycopycode opened a new issue, #2459:
URL: https://github.com/apache/brpc/issues/2459
**Describe the bug (描述bug)**
在运行server和client之后有时测试会失败，不知这是否是正常的
**To Reproduce (复现方法)**
按照[rdma文档](https://github.com/apache/brpc/blob/master/docs/cn/rdma.md)配置
`./server 2333 -rdma_memory_pool_initial_size_mb=512 `
`./client 172.31.50.174:2333 -rdma_memory_pool_initial_size_mb=512`
我本机按默认内存1024MB会分配内存失败
**Versions (各种版本)**
RoCE ubuntu 虚拟机
`lfw@lfw-vm:~$ rdma link show
link rxe_0/1 state ACTIVE physical_state LINK_UP netdev ens33 `
**Additional context/screenshots (更多上下文/截图)**
可以看到client的运行情况有时出现Fail to write into Socket，有时出现127.0.0.1:43942(no auth)
requests for profiling
