Node synchronization problem, always keep a distance of about 100 from the latest height

Node synchronization problem, always keep a distance of about 100 from the latest height

The node has been running normally, and there is no error message logs.
When querying in the console, the currentBlock and highestBlock always have a difference of more than 100 block heights. This situation has been maintained for more than a week.
I tried restarting geth, but it didn't solve the problem.

I have similar problem. I am trying to re-sync node since last week. The process few time crashed and few time got stuck about 100 blocks from the head.

> eth.syncing

{
  currentBlock: 11920443,
  highestBlock: 11920560,
  knownStates: 571082961,
  pulledStates: 570992471,
  startingBlock: 11918187
}

The states keep advancing as well as currentBlock but it always seem to keep about 80-100 blocks behind the tip
