?Thanks Cliff for your input. However I do not allocate anything after the device has started. I only create two mempool, one per socket, and they are both looked up fine in the secondary,. Moreover, my setup works without any problem when I use two ports on the same NUMA node/same physical PCIe NIC card.

Your secondary can then look up the name of them. If you try to create one of these in the secondary process, you will see the errors you had above. I ended up making sure all rte structures were created in my primary, and the secondary simply requested things to be created. This can be done using the IPC library.

If I don't touch any packet on the primary, this shouldn't cause any problem, right? We want to use all of the CPU cores for processing. The primary is only a controller. Tom
