<p>I had the same error. I don't know exactly what this is about. But I just deleted the whole db folder and created node.socket again. Resync, then it's back</p>

<p>I successfully setup a testnet node over the weekend, all was running fine - I was able to create wallets and perform transactions etc.
However when I try to run the node today I am getting some errors, I haven't changed any config, I literally just turned the machine off and when I booted back up it didn't work (see error at the bottom)</p>
<p>I have downloaded the latest config files, I also deleted some data from the immutable folder in /db  - it synced up again but then gave the same error</p>
<p>I hope someone can help, many thanks in advance.</p>

Out of mere curiosity, why 1.27.0 and no 1.29.0?
