[Rdo-list] compute node secure message flood rootwrap.conf ovs-ofctl dump-flows br-int table=22

Hello, On our compute nodes the /var/log/secure log get flooded with the same kind of messages: Mar 22 10:17:57 xxx sudo: neutron : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ovs-ofctl dump-flows br-int table=22 Mar 22 10:17:59 xxx sudo: neutron : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ovs-ofctl dump-flows br-int table=22 Mar 22 10:18:01 xxx sudo: neutron : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ovs-ofctl dump-flows br-int table=22 Mar 22 10:18:03 xxx sudo: neutron : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ovs-ofctl dump-flows br-int table=22 Mar 22 10:18:05 xxx sudo: neutron : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ovs-ofctl dump-flows br-int table=22 Mar 22 10:18:07 xxx sudo: neutron : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/neutron-rootwrap /etc/neutron/rootwrap.conf ovs-ofctl dump-flows br-int table=22 Any hint what's the purpose of this and how to fix it?
