The problem is that with DPDK version 22.11.4 (we use the official Debian stable repositories), the memory usage grows very high. On our regular nodes with DPDK version 22.11.3, OVS usually consumes less than 3GB of RSS. However, with DPDK version 22.11.4, on some of our nodes it gradually grows to 100GB. All nodes use OVS 3.1.0 (both those with the memory issue and those without it). Also, for some OVS ports in problematic nodes, we get no statistics with DPDK-22.11.4 (ovs-ofctl dump-ports shows ? for rx bytes). We tried DPDK-22.11.5, but these issues were not fixed. Is there a known solution for this problem or are these issues fixed in the upcoming version? Thanks, Ali
