Geth, BSC full node sync "State sync in progress" stuck at 70%

Question

I am doing a BSC full node sync using the following command:

/mnt/raid/bscdata/geth --syncmode full  --config /mnt/raid/bscdata/config.toml --datadir /mnt/raid/bscdata/node --cache 32000 --rpc.allow-unprotected-txs --txlookuplimit 0

The sync process stopped importing new block headers at ~26.000.000 block and started a new process called "State sync in progress". From my understanding, a full sync will import the blocks first and then process those blocks after, from the internet I found that this process starts near the end of import process so in my case it started at 26m block. So this is ok.

The problem though is that it shows eta=191h43m49.052s which is huge, and I found that people manage to process it just a few hours.

LOG

t=2023-04-10T10:03:59+0000 lvl=info msg="State sync in progress"                 synced=0.07% state="403.58 MiB" accounts=1,165,[email protected] slots=1,578,[email protected] [email protected] eta=191h43m49.052s

Also, my cpu is at 3% chilling

How can I speed up the process? should I run geth without --syncmode full?

UPDATE, will see how it runs increasing cache to --cache 48000, and adding --gcmode full

After 1 day it managed to do some progress

t=2023-04-12T08:50:22+0000 lvl=info msg="State sync in progress"                 synced=74.82% state="408.35 GiB"  accounts=164,259,[email protected] slots=1,841,074,[email protected] codes=1,611,[email protected] eta=14h52m37.265s

But it stopped here for 12h, and now it's just importing new blocks. cpu is at 0%

Answer 1

There is some stuff you can try, the easier one would be to use your node with --syncmode fast option instead of --syncmode full it will allow you to download only the recent state of the chain, you can also check that you have a sufficient number of peers --maxpeers 100, and also check your network connection.

Increase the cache might help but in any case the ETA you see may not be entirely accurate, as it can fluctuate during the syncing process.

Answer 2

The issue was that I was connected to bad peers. I solved it by updating static peers and restarting geth service.

peers can be found here https://api.binance.org/v1/discovery/peers

also updated geth to the latest version
