Found in production. Yes really. Due to some borked LXC integration, my snikket host reports ``` MemTotal: 9007199254740991 kB MemFree: 9007199254690591 kB MemAvailable: 9007199254690591 kB ``` That is more than 1024 TiB, so it tries to go further up in the scale, which then causes a Guru Meditation because of the uncaught IndexError.
