lnd: [bug]: CRITICAL! Unable to process chain reorg / too many witness items to fit into max message size

Background

lnd does not process new blocks.

lnd:

2022-11-01 12:02:54.658 [ERR] LNWL: Unable to process chain reorg: unable to get block 000000000000000000070742427fa10ec3c66d006160155a704d9f56d090a3ea: MsgTx.BtcDecode: too many witness items to fit into max message size [count 500003, max 500000]

My bitcoind knows about block height 761255, but lnd and mempool.space are stuck at 761248.

lnd v0.15.3-beta
bitcoind v23

I’m running neutrino, and not seeing the issue:

walter@fluffy:~$ lncli  getinfo | grep synced
    "synced_to_chain": true,
    "synced_to_graph": true,
walter@fluffy:~$ lncli  getinfo | grep block
    "block_height": 761264,
    "block_hash": "000000000000000000072cabab0aac7c6b00db0664b82edc77d3252634fcba8a",

I bumped to 0.15.4, it fixed the issue. (our own build)

I’m guessing this is a btcd issue? Everything seems to be fine on bitcoin

no, i`m running bitcoin core v22.0 and having the same issue.

Hi,

My all nodes are in a state:

l getinfo|grep synced
    "synced_to_chain": false,
    "synced_to_graph": true,

CRITICAL bug is number # 2 ? 😃))

Yes, the btcd issue is linked above.

C-Otto on Nov 1, 2022

I’m pretty sure all (recent) lnd installations are affected by this.

C-Otto on Nov 1, 2022

Would it be possible to modify lnd so that it skips validation on blocks received from the chain backend? Just reading about Eclair’s exposure to this class of bugs: https://github.com/ACINQ/eclair/pull/2473#discussion_r1011530186
