Hi, We are using openstack rocky. We are facing a critical issue. Something happened in our infrastructure and now huge fake tap devices are creating and deleting continuously for some of our compute node. following logs are generating continuously. all the services/VMs are up and running. Due to this, snmp service is not working properly.
after rebooting one compute node the issue resolved but all the compute node we are not unable to restart now. Any idea to resolve the issue without restart the compute node. # tail -f /var/log/openvswitch/ovs-vswitchd.log 2022-01-10T04:59:10.689Z|679747376|bridge|INFO|bridge br-int: added interface
