Comment 3 for bug 1896203

The maintenance task that is failing is mentioned in the traceback: neutron.plugins.ml2.drivers.ovn.mech_driver.ovsdb.maintenance.DBInconsistenciesPeriodics.check_for_igmp_snoop_support

Unfortunately I don't know what is causing that issue - the root cause for the error itself seems to be an entry in Logical_Switch table without any configuration:

```
_uuid : 6ba3f2a7-fb25-481e-a261-a3501c4c1054
acls : []
dns_records : []
external_ids : {}
forwarding_groups : []
load_balancer : []
name : ""
other_config : {}
ports : []
qos_rules : []
```

This entry could have been created during my ovn stress tests, deleting it from Northbound DB fixes that maintenance task, however adding an ERROR-level message could be useful here, or some other task that clears up database from dangling entries?
