Hi,

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.
