The Zip will be retried on next upload.pl call where it first tries to
upload all "old" zips left over from previous runs (aborts). This step
is rate limited by the exponential backoff already. Failure counts are
saved between sessions so it gets slower each time before returning to
tilesGen.pl
But you are right, it can take a few tilesets until the rendering slows
down noticeably, but not too many, since every tileset generates 2 zips,
which means after 3 tilesets with no successful upload you have a
timeout of 2**6 already, next tileset would be 2**12 (over an hour)
between upload tries.
