If a CL pushes the (compressed) size of the tree over a limit, trybots fail with something like:

(From https://go-review.googlesource.com/c/website/+/365135/2//COMMIT_MSG#14.)

But it's currently considered a retryable problem, and since #13026 hasn't been resolved yet, it keeps on retrying forever until someone removes the Run-TryBot request.

Even if the issue above is fixed, coordinator should classify this as a non-retryable error and not keep retrying.
