I've been syncing the ethereum blockchain for over a week now and it has stopped downloading blocks but continues to download structure. When I restart it, it resumes downloading blocks but will only get to within 50 blocks, of the nearly 4 million, before stopping again. at this point I am at 5,731,656 of 5,731,668 of chain structure.
Does this chain structure have anything to do with completing the download and if so how high does it go?
Should I keep restarting it and hope it eventually completes the last few blocks or wait for a given number of coin structure to complete ?
