This usually happens when your build cache fills up quickly. I’ve had an implementation to automatically destroy the builder when this error happens for a while now, and I should probably get it deployed sometime next week.
A quick alternative is to use Depot remote builders, since they automatically remove old build caches when you get close to the limit.
A good solution would also be to check why your build cache is filling up so quickly. We automatically delete remote builders once a day or so, so it’s possible you’re uploading a lot of unnecessary context up.
