Log errors related to Unknown column with Domain Mapping

We have multisite installed with 10 blogs, using https. The sites all 'work' like they are supposed to, but we just noticed that any visit to the primary multisite domain is creating a LOT of errors. Every visit to front end or admin creates about 40 lines of errors. Most look like the following. Please advise:
