How did you sync your chain?

Anything interesting happen before this that may have corrupted the DB?

[chenzongxiong]

The database is easily corrupted across different version of ironfish.

From what I observed, 1. If someone removes LOCK in the ~/.ironfish/*/LOCK forcibly, and starts another node, then the database will be corrupted. 2. When I send transactions for an account, which tokens are minted by other nodes. The local node won't witness latest tokens, I have to run ironfish accounts:rescan to sync account first. This will cause nullify error. I think someone already reported. 3. And if the second case takes place, then the database can also easily be corrupted. I have no idea.

I strongly suggest the official binary should trap the signal of SIGINT, SIGTSTP, SIGKILL. Also provide a easier way to setup for systemd to make the process run smoothy.

We don't support 1) - if you are manually deleting files in that data_dir, that is user error if something breaks.

Would love to dig into 2) - do you have a set of steps to reproduce this? I think "tokens minted by other nodes cause an error" is likely too broad. There's probably something more specific about your particular workflow.

We've made significant changes to the wallet since this issue was created. Please create a new issue if you've run into this again on a more recent version. Thanks!
