New node sync crashed with 'key 012f002f626c6f636b2d72656c6...not found' (v0.11.11)

Hi,

I upgraded my kaspad from 0.11.9 to 0.11.11 (by precompiled kaspad binary for linux) and after few tens of minutes I end up with error below. I have Debian Linux Bullseye.

This error happends immediately after ./kaspad --utxoindex.

Btw, i deleted (moved) previous datadir2 content, because just after upgrade kaspad binary and start it again, after 2-3 hours there was only lot of "Connecting to... lot of IPs", so kaspad was not unable to sync. After that i deleted datadir2 content and restarted kaspad. Kaspad started to sync from 2022-01-25 which was OK, but after tens of minutes it crashed with error below.

./kaspad --utxoindex;

Hello!
I'm facing the same issue. After running kaspad for many days it suddenly died (between 2022-03-04 and 2022-03-07). This morning I tried restarting kaspad and got the reported error message:

As I said the daemon has run for many days before dying with this error, so it should not be in syncing phase.

Here are version informations:

• OS: Debian 11 (fully up to date at 2022-03-07 09:00 UTC)
• kaspad 0.11.11 (precompiled version downloaded from GitHub)

[isezen]

I had faced same issue today with v0.12.6. Any solution?

[tomekmak]

Same here is there any solution (2.12.1 version)

[someone235]

Same here is there any solution (2.12.1 version)

Does resetting the DB fixes the problem?

I just did reset database, reinstalled KDX and now i cant open the app - shows only in taskbar. "Show" is grayed out.

I just installed it from source on (Ubuntu 22.04.1 LTS), launched it from scratch, and after synchronizing the blockchain I received a message:
