Hello jingjunLi,

Thanks for the details. I hope my issue has been resolved.

Hello Team,

Now currentBlock: 39970716 highestBlock: 39970455,

eth.syncing.highestBlock - eth.syncing.currentBlock -302

currentBlock (39970716) is greater than highestBlock

please let me know how to resolve this?

jingjunLi commented 3 months ago

when txIndex is in progress it is not synced yet, the highestBlock may less than the currentBlock. txIndex could take a few hours.

@joeylichang can we just remove the following part of code in function: gcKVStore(...)?

// Step into the future and delete and dangling side chains
if frozen > 0 {
...
}
