This is a bug. Please report it at:

Sorry, I can't show more logs, I runned it in tmux.

After restart I've got: DB has been previously marked as corrupted, attempting repair

Seems that this function panics:

https://github.com/openethereum/openethereum/blob/698e696a3a5a624a61e2907363e6934d06005173/ethcore/verification/src/queue/mod.rs#L291

And this cached in the .join

Maybe we need just to error! instead of panicking at this level.

The expect after join is just propagating the panic of the verifier thread, this is the Fail-Fast strategy, I don't think this should be changed. I don't know why the verifier thread panicked, could be a db corruption
