Hello everyone. I have found issues with my IP Multicast Storm (generator of valid IP packets) and UDP Broadcast Storm. Problem is, whenever threshold rate is breached (around 90 Mbps), both ports go down. I am using Freescale P1010 Processor and Marvell 88E1512 PHY for Ethernet with Linux 3.18.9-rt4 kernel build. I get this message as a result: “NOHZ: local_softirq_pending 102, a page allocation failure is reported.” This means that system memory is depleted while I have over 200 Mbps of free space. What might be the issue here?
