DLC Teardown context deadline exceeded

Our jobs using Docker Layer Caching are consistently failing at teardown. Saving fails after about 11 seconds and says the context deadline has exceeded. I can find no documentation about any time cutoff for DLC saving. We are on a paid plan.

Output of the stop is pasted below.
