Hi All, While testing performance with eventdev, I am seeing a crash in dpdk service core. Test scenario is given below 1) DPDK 1805 2 Eventdev ordered Queues & 2 Ports 2) 2 Workers threads + 1 Service core for running scheduling. 3) 1st worker is getting packet from NIC and enqueueing to Q1 *.... [PLEASE FILL THIS]* 4) Packet rate of 5.6Mpps (Pkt size 64 bytes)
