This is a hypervisor crash (QEMU) so not something we can do anything about in LXD itself :(

We've seen this a few times in the past, I'd recommend you try to increase limits.memory to 2GiB or more, we've seen this help in the past.

If that doesn't help, look at dmesg for a potential hardware/kernel error.

Let us know if bumping the amount of memory helps with the issue, if it doesn't, it may be worth reporting the crash to QEMU upstream.
