WordPress database error Duplicate entry

This is the error being logged in my production server (replaced IP with X’s):

It doesn’t happen that often, but as I recall, it does happen when I’m logged in 2 separate browser pages/browsers to both my WordPress website and my WordPress dashboard or twice to my WordPress website or twice to my WordPress Dashboard.

It’s not a showstopper, but it does generate a server error log entry, so I hope a check can be added to avoid trying to insert a duplicate user IP into the db.
