Had this problem on one of my servers (the only one running bind on Bionic), installed this proposed-update package on Thursday morning, 31st, and have not seen this error since then. Searching through my logs I saw this error appearing at least every second day - often more than once a day - and have not seen it now for more than four days!

IMO this fixes the issue.
