I am facing problem with one of my application with DPDK. Please find below details of my setup, Host - Ubuntu 14.04 with KVM-QEMU(4.2.0-27-generic) 64 bit Guest - Ubuntu 14.04(3.13.0-24-generic) 64 bit DPDK - 16.04 running in VM Huge page - 2000(2MB) on guest VM Intel NIC 350 T-4 Configured grub parameter - intel_iommu=on, iommu=pt Using 4 core with DPDK Now when I start traffic, DPDK start processing traffic and for 15-20 minutes everything works fine. Then after a while DPDK stops processing traffic and I can see error on log like tx_burst failed at lcore(1), port (0). I checked DPDK process health and I do not see any problem with that like hang or crash. Any help or lead will be appreciated.
