我也遇到了这个问题，是在模型训练场景上。
1）server端报错"[rdma_endpoint.cpp:575] Fail to read Hello Message from
client:Socket{id=34359739185 fd=1393 addr=10.28.195.43:59658:4333}
(0x0x7fa6b12e0f40) 10.28.195.43:59658: Unknown error 1014 [1014]"
2）client端报错“][ 5729][rdma_endpoint.cpp:773] Memory not registered for rdma.
Is this iobuf allocated before calling GlobalRdmaInitializeOrDie? Or just
forget to call RegisterMemoryForRdma for your own buffer?”，
但是我的rpc请求没有使用attachment。
我用的brpc版本是1.9。
