Stuck sync with SputnikVM #689

Closed splix closed 5 years ago

splix commented 5 years ago

Geth with stopped to sync, restarts, network change, adding new 100% working peers, nothing helped for a few days of experiments.

For hours:

2018-11-08 22:44:40 Sync      #6863284 of  #6896083 429a591e     0/   0/ 0 blk/txs/mgas sec  7/25 peers

Switching to standard EVM fixed the problem.

Two things that looked strange with geth --sputnikvm:

1) Fork

It stopped at block 6863284 with hash 0x429a591eeb457fda65b95640b9f6c367a2ad9e7fe3ffb6f2eaef18d9ed8adc57. Which is a stale block, main chain has 0xf2aa3f9cdfc1642d1f6a1cdda790c5a131c7bd9746bd4efe05d52b93b2d15cfd at this height.

Even if I do geth rollback 6863280 it reaches block 6863283 (which is right before split) and stops again.

2) Invalid hash chain

In logs nothing suspicious, except many lines like:

W1108 23:06:40.339742 eth/downloader/downloader.go:499] Synchronisation with [peer:892daaf36fc1d38e@[Parity-Ethereum/v2.0.9-stable-09f7757-20181028/x86_64-linux-gnu/rustc1.30.0] eth/63][eth/63] terminated after 1.010391811s
W1108 23:06:40.339760 eth/downloader/downloader.go:403] Peer 892daaf36fc1d38e: drop: retrieved hash chain is invalid

And eventually is looses all peers.

Thanks for reporting. Looking at it.

I've tried to reproduce, and failed to, although did get an identical-seeming issue at block #6921898.

It seems I've just got the same problem again:

Disabling SputnikVM fixed the problem
