Initially, packets were transmitted properly, but after a few hours, the issue is seen. The function rte_eth_tx_burst is called in the below API: u32 tx_burst_vector_internal (vlib_main_t * vm, 191 dpdk_device_t * xd, 192 struct rte_mbuf **tx_vector) Link: https://docs.fd.io/vpp/17.07/de/d54/plugins_2dpdk_2device_2device_8c_source.html#l00190 I would like to know if there is an API available to check what exactly is happening in the problematic case? Please help to give some pointers for me to check. Thanks in advance. Regards, Aswin
