**Describe the bug** 单机回环执行rdma_performance测试，具体执行命令如下 taskset -c 50-86 ./server -use_rdma 0 -thread_num 37 & taskset -c 6-32 ./client -thread_num 27 -queue_depth 78 -attachment_size 16788 -use_rdma 0 -connection_type pooled 会偶发报错类似如下： 2026-06-25 14:51:11,661 INFO: 49491 ScriptThread Module:session_manager.py:run_cmd[367] Log:kp_receive:I0625 14:51:10.816046 23666 0 src/brpc/server.cpp:1262 StartInternal] Server[DummyServerOf(/home/ci/brpc/pkgs/example/rdma_performance/client)] is serving on port=8001.
