Grabbed the logs from the crashdumps. As mentioned by @petevg there is nothing we can use here for diagnosis.
The problem is on the machine that we have no information for. The controller logs show that the machine-18 in the kubernetes model never tried to connect. This normally indicates some networking or cloud-init issue on the started instance.
Without access to the instance that has had the problem, there is nothing we can do.
