Thank you for your reply. I tried to change num-tx-queues from 2 to 5, but it got a SIGSEGV, the backtrace is: #0 0x00007fffb453ff89 in rte_write32_relaxed (addr=0x80007ffffef0, value=0) at ../src-dpdk/lib/eal/include/generic/rte_io.h:310 #1 rte_write32 (addr=0x80007ffffef0, value=0) at ../src-dpdk/lib/eal/include/generic/rte_io.h:373 #2 vmxnet3_enable_intr (hw=0xac03b0600, intr_idx=4294967262) at ../src-dpdk/drivers/net/vmxnet3/vmxnet3_ethdev.c:210 #3 0x00007fffb4544d35 in vmxnet3_dev_rx_queue_intr_enable ( dev=0x7fffb5186980 <rte_eth_devices>, queue_id=0) at ../src-dpdk/drivers/net/vmxnet3/vmxnet3_ethdev.c:1815 #4 0x00007fffaff4bbf2 in rte_eth_dev_rx_intr_enable (port_id=0, queue_id=0) at ../src-dpdk/lib/ethdev/rte_ethdev.c:4740 #5 0x00007fffb49f4564 in dpdk_setup_interrupts (xd=0x7fffbdbb2940) at /home/chenweihao/vpp_dev/src/plugins/dpdk/device/common.c:336 #6 0x00007fffb49f4430 in dpdk_device_start (xd=0x7fffbdbb2940) at /home/chenweihao/vpp_dev/src/plugins/dpdk/device/common.c:411 #7 0x00007fffb49ff713 in dpdk_interface_admin_up_down ( vnm=0x7ffff7e2b828 <vnet_main>, hw_if_index=1, flags=1) at /home/chenweihao/vpp_dev/src/plugins/dpdk/device/device.c:476 #8 0x00007ffff70d60e8 in vnet_sw_interface_set_flags_helper ( vnm=0x7ffff7e2b828 <vnet_main>, sw_if_index=1, flags=VNET_SW_INTERFACE_FLAG_ADMIN_UP, helper_flags=0) at /home/chenweihao/vpp_dev/src/vnet/interface.c:470 #9 0x00007ffff70d645a in vnet_sw_interface_set_flags ( vnm=0x7ffff7e2b828 <vnet_main>, sw_if_index=1, flags=VNET_SW_INTERFACE_FLAG_ADMIN_UP) at /home/chenweihao/vpp_dev/src/vnet/interface.c:524 #10 0x00007ffff710515f in set_state (vm=0x7fffb6a00740, input=0x7fffa9f84bb8, cmd=0x7fffb7180850) at /home/chenweihao/vpp_dev/src/vnet/interface_cli.c:946 #11 0x00007ffff7e72257 in vlib_cli_dispatch_sub_commands (vm=0x7fffb6a00740, cm=0x7ffff7f6a770 <vlib_global_main+48>, input=0x7fffa9f84bb8, parent_command_index=20) at /home/chenweihao/vpp_dev/src/vlib/cli.c:650 #12 0x00007ffff7e71fea in vlib_cli_dispatch_sub_commands (vm=0x7fffb6a00740, cm=0x7ffff7f6a770 <vlib_global_main+48>, input=0x7fffa9f84bb8, parent_command_index=7) at /home/chenweihao/vpp_dev/src/vlib/cli.c:607 #13 0x00007ffff7e71fea in vlib_cli_dispatch_sub_commands (vm=0x7fffb6a00740, cm=0x7ffff7f6a770 <vlib_global_main+48>, input=0x7fffa9f84bb8, parent_command_index=0) at /home/chenweihao/vpp_dev/src/vlib/cli.c:607 #14 0x00007ffff7e7122a in vlib_cli_input (vm=0x7fffb6a00740, input=0x7fffa9f84bb8, function=0x0, function_arg=0) at /home/chenweihao/vpp_dev/src/vlib/cli.c:753 #15 0x00007ffff7ef7e23 in unix_cli_exec (vm=0x7fffb6a00740, input=0x7fffa9f84f30, cmd=0x7fffb71815b8) at /home/chenweihao/vpp_dev/src/vlib/unix/cli.c:3431 #16 0x00007ffff7e72257 in vlib_cli_dispatch_sub_commands (vm=0x7fffb6a00740, cm=0x7ffff7f6a770 <vlib_global_main+48>, input=0x7fffa9f84f30, --Type <RET> for more, q to quit, c to continue without paging--<RET> parent_command_index=0) at /home/chenweihao/vpp_dev/src/vlib/cli.c:650 #17 0x00007ffff7e7122a in vlib_cli_input (vm=0x7fffb6a00740, input=0x7fffa9f84f30, function=0x0, function_arg=0) at /home/chenweihao/vpp_dev/src/vlib/cli.c:753 #18 0x00007ffff7efdfc5 in startup_config_process (vm=0x7fffb6a00740, rt=0x7fffb9194080, f=0x0) at /home/chenweihao/vpp_dev/src/vlib/unix/main.c:291 #19 0x00007ffff7ea2c5d in vlib_process_bootstrap (_a=140736084405176) at /home/chenweihao/vpp_dev/src/vlib/main.c:1221 #20 0x00007ffff6f1ffd8 in clib_calljmp () at /home/chenweihao/vpp_dev/src/vppinfra/longjmp.S:123 #21 0x00007fffac516bb0 in ??

I tried to change num-rx-queues and num-tx-queues to 4, then SIGSEGV not happened. I applied the patch https://gerrit.fd.io/r/c/vpp/+/38529 , and the problem of redis 6.0 seemed still exist, the stack backtrace is same with https://lists.fd.io/g/vpp-dev/message/22731
