In order to validate that data on both network is similar, I need to capture traffic on the 2 NIC ports simultaneously, no matter if the result is 2 pcap files. Since dpdk-pdump seems to work for one single port, I've tried to start 2 pdump processes simultaneously, which leads to a `Cannot reserve memory` msg for one of these. I'm not very familiar with how mem pools and queues work. But I feel like there is a clever way to handle that. Can someone give a hint? Best regards, PK
