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

[Marcin Mirecki]

Hello Misak,

The openvswitch team tells me this is a known ovs problem.
It is fixed by patch:
https://github.com/openvswitch/ovs/commit/bbf219ef584a102fde5150defab3a769a6a44981
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.

Thanks,
Marcin
