BAD BLOCK cant syncing

[serfiraz21]

at 2021-12-03T15:24:32+0000 has given "########## BAD BLOCK #########" message and has been out of sync.
From 15:24 UTC to now still keep giving Bad Block message.

i have tried these steps:

1.Used with diffsync enabled (already enabled).
2. Restated geth client. ( 3 -4 times)
3. Restart without diffsync flag

I use geth v1.1.6. steps above doesnt resolve.

Same here, started happening on two of my nodes 3 hours ago.

Use debug_setHead solution mentioned in #507

[ko0f]

Even if that works, that's a workaround. There's a bug that causes this to occur and stop nodes from syncing.

start with *diffsync disabled, rewind the chain the way @khelle suggested and it should work.

*with diffsync on it can happen again after rewind.

few people in the discord chats had the same bad block problem

So diffsync is the problem here?

The same situation also appeared to me. Since version 1.14, test nodes and main network nodes are prone to sudden bad blocks and fail to synchronize.

Use debug_setHead solution mentioned in #507
