Index 8 out of range for slice of length 0

[irriden]

This happens on a loop after I try to connect a second signer while a first signer does keysends with the broker.

This might be hard to reproduce, might be a one-off - not quite sure what happened.

The idea now is to unplug signers at random points during the keysends.

Just reproduced, this likely is caused by unplugging the signer at a bad point in execution - and leaving the sd card with corrupted data. Restarts don't fix this problem.
