Your Actions

Some time after logging off after a few hours of running the server and playing on it, the server crashed. The day after, after turning my laptop on and starting the server (no other app should open the same file), it crashed after a few minutes of running. The log says the same error even after restarting the laptop, or even loading a backup.

What happens if you move the world over to a fresh install of the server, or even updated nightly? The error in the log is not exactly clear on cause.
