When testing the recreation of 'chassis' table entry by 'ovn-controller- vtep'. The removal of 'chassis' table entry by the 'ovn-sbctl' could cause 'Broken pipe' warning in ovsdb-server.log. This is due to the race between 'ovn-sbctl' exiting and 'ovn-controller-vtep' adding the chassis back. So, if the 'ovn-sbctl' exits right when the ovsdb-server tries to send update of readd of the deleted 'chassis', the sending will fail with 'Broken pipe' error.
