Fast syncing never stop

Question

I have run geth --fast --cache=1024 for a week and I think I am almost complete: etherscan.io shows:

LAST BLOCK 4005552

and my eth.syncing shows:

{
  currentBlock: 4005449,
  highestBlock: 4005553,
  knownStates: 1157252,
  pulledStates: 1141319,
  startingBlock: 4005266
}

But geth --fast never change to normal and keep on getting new state only:

INFO [07-11|09:20:49] Imported new state entries count=3 flushed=4 elapsed=0s processed=1273621 pending=10500 retry=2 duplicate=1200 unexpected=2461

What should I do? Can I just stop and run normal geth without --fast flag? Or can I try mining already?

I wrote a tiny python script to overview the process. It's here https://github.com/hayorov/ethereum-sync-mertics

My output:

Answer 2

I had exactly such problem and finally found that source of problem is my system time! I simply solved the problem with enabling network time synchronization on my ubuntu with following command, and then restarting geth.

timedatectl set-ntp true
