shortly after syncing with 0.21.3 litecoin will stop with the above error. 0.21.2.2 continues to run after syncing.

could be a problem on my side but i wanted to post this for FYI

In 0.21.3 can you try console command reconsiderblock with the previous block to the one you're having a checksum mismatch on?

unfortunately i'm not fast enough to get to the console before we bomb and exit.

i tried doing it with 0.21.2.2, i.e.
reconsiderblock 4aaedcd03df6599733cb067c1dc6222aafbce7a26b06af508e098ba6d39529cf

and then re-running 0.21.3 but we bomb and exit for the same block - but thanks for the idea

I'm having the same issue is there any workaround on how to upgrade to v0.21.3 ?

[losh11]

I would try resyncing from scratch. Delete the blocks directory.

gituser are you have the problem with the same block (1228431) or a different block?

if it is a different block could you let us know which one? thanks!

I'm having exactly same error when trying to run v0.21.3:

same error, same block, macOS. no fix?

[gituser]

same error, same block, macOS. no fix?

unfortunately for me workarounds listed in this thread didn't help, I had to take synced blockchain from other server

[arshad-deriv]

I can see there is a new release https://github.com/litecoin-project/litecoin/releases/tag/v0.21.4 but I was not able to see if this issue is fixed already or not?

[losh11]

@arshad-deriv sorry I'm not able to reproduce this issue. Have you tried resyncing from scratch?

[Sayrix]

I don't know if it was the same block, but some days ago my litecoin node crashed with a similar error i think, i tried to resync the block headers but when it was trying to resync the block headers i was getting a segfault error so i tried to resync completely which took 1 day but after that it worked. About the segfault error i was using litecoind 0.21.3 aarch64 but i now upgraded to 0.21.4

[arshad-deriv]

@arshad-deriv sorry I'm not able to reproduce this issue. Have you tried resyncing from scratch?

@losh11 I did not need to resync from scratch so far but I have not upgraded the node just to avoid any unforeseen issue like mentioned above that it gives an error on some specific block and needs to resync from scratch afterward which is time-consuming. May I know if upgrading to 0.21.4 fixes the issue?

[Garfield-de-Kat]

Having the same issue here,
I'm using an old chain-state that was last synced, four and a half years ago.
It crashes immediately when opened.
But remains active in the background and does synchronize with the blockchain
