Hi Ken, here is the error syndrome 0x04 meaning: 0x4: Local_Protection_Error "This event is generated when a user attempts to access an address outside of the registered memory region. For example, this may happen if the Lkey does not match the address in the WR." Looks like wrong buffer was passed to the NIC for a packet acquisition. Could you please share more details on your test case? What is the traffic pattern? What is Rx/Tx queues config? mbufs?

Once this condition is hit, the rxq->err_state var in the mlx5 PMD is never cleared, and the rx just loops around never receiving any further packets. It's not clear what's causing the initial CEQ error, as it can take upwards of an hour to occur. The full log entry is: Unexpected CQE error syndrome 0x04 CQN = 256 SQN = 4679 wqe_counter = 2149 wq_ci = 3294 cq_ci = 42609 MLX5 Error CQ: at [0x292d26000], len=16384 The NIC is: NVIDIA ConnectX-7 HHHL Adapter card, 400GbE / NDR IB (default mode), Single-port OSFP, PCIe 5.0 x16, Crypto Enabled, Secure Boot Enabled Part number: MCX75310AAC-NEA_Ax Firmware: 28.36.1010 OFED Version: 24.04-0.6.6.0 DPDK Version: 23.11.0 This issue was previously mentioned in this post: https://mails.dpdk.org/archives/users/2022-October/006779.html Can anyone please help shed some light on this?
