This error message is related to the Data Plane Development Kit (DPDK) and indicates that there was a problem initializing the mbuf pool, which is used by network interfaces to manage packets. This error can occur for various reasons, including insufficient resources or configuration issues.
Here are some possible solutions:
Check if your system meets the DPDK’s requirements in terms of memory, CPU, and other hardware resources. Ensure that there is enough memory available to initialize the mbuf pool.
Verify that you have installed the correct driver for your network interface card (NIC). Also, check if your NIC supports DPDK and whether it is configured correctly.
Try increasing the number of mbufs allocated by changing the values in
rte_mempool_create()orrte_pktmbuf_pool_init(). For example, you can increase the number of mbufs with--mbuf-sizeand--total-num-mbufsparameters when launching your application.Ensure that you are running the latest version of DPDK and any relevant libraries.
If none of these steps work, try seeking support from DPDK community forums or mailing lists for further help with troubleshooting this issue.
Remember that these steps are not exhaustive and may not solve all cases of “Cannot init mbuf pool” errors. Therefore, it’s important to investigate thoroughly and seek additional support as needed.
