Re: [ovirt-users] OVS error logs after upgrade to 4.2

Hello Misak, The openvswitch team tells me this is a known ovs problem. It is fixed by patch: https://github.com/openvswitch/ovs/commit/bbf219ef584a102fde5150defab3a76... merged in master/branch 2.8/branch 2.7. Looking at git history this is not yet released. It should be included in 2.7.4 when it's out.
