Created attachment 271 [details] Secondary lldb process output Linux: AlmaLinux 9.3 Kernel: 5.14.0-362.8.1.el9_3.x86_64 Software version: rdma-core-48.0-1.el9.x86_64 dpdk-v22.11(tested on git branch v23.11-rc4 as well) Hardware: Mellanox Technologies MT27800 Family [ConnectX-5] Running two testpmd processes at the same time causes the secondary process to crash with a segmentation fault from the libmlx5.so library. Two ports on a Mellanox MT27800 card are configured to be used by both testpmd apps. The two separate instances are launched: 1. dpdk-testpmd --proc-type=primary 2. dpdk-testpmd --proc-type=secondary I am not sure if this is a rdma-core issue which contains the libmlx5.so library where segmentation fault is thrown from. The primary dpdk process runs without any issues and there are no segfaults. The rte_eth_stats_get function only throws an error on the secondary process, not on the primary process. Attached is the lldb output when running a debug build secondary process with lldb. Running dmesg also shows that there is a segfault: dpdk-testpmd[67695]: segfault at b077f90 ip 00007f1ae42069e4 sp 00007ffcd49903b8 error 4 in libmlx5.so.1.24.48.0[7f1ae41b5000+5a000] likely on CPU 0 (core 0, socket 0) Code: 77 90 0f b6 d2 48 8d 05 7a a3 00 00 44 0f be 24 10 e9 7c ff ff ff e8 fb f3 fa ff 66 66 2e 0f 1f 84 00 00 00 00 00 f3 0f 1e fa <48> 8b 07 49 89 d2 4c 8d 0d 4f 88 01 00 48 8b 10 48 8b 92 98 02 00
