iMac High Sierra - host kernel panic when adding load to guest

[codekunst]

Steps to reproduce: Create a simple Virtualbox with vagrant:

Vagrant.configure("2") do |config|
  config.vm.box = "bento/ubuntu-16.04"
  config.ssh.forward_agent = true
  config.vm.network :private_network, ip: "192.168.91.21"
  config.vm.provider "virtualbox" do |v|
    v.name = "maschinenring test"
    v.customize ["modifyvm", :id, "--memory", "4096"]
  end
end

ssh into it and install the stressapptest

sudo apt-get install stressapptest

Runn the stressapptest with

stressapptest -s 9000 -m 8 -C 8 -W --findfiles -i 2 -M 4500

Wait for one to two hours untill the host system rects with a cernel panic. I have also attached three panic reports. For me they it looks like the vm just create some random errors in the kernel memory space. I reproduced this bug on three iMacs. All software was up to date , the iMacs do not crash in normal usage or with load testing on the host system.

I haven't seen this happening before the upgrade from Sierra to High Sierra.

Softweare Versions:

• High Sierra version: 10.13.3 (17D102)
• Virtualbox: 5.2.8
• Vagrant: 2.0.3

As the test Version of Virtualbox on https://www.virtualbox.org/wiki/Testbuilds is linking to https://www.virtualbox.org/download/testcase/VirtualBox-5.2.9-121224-OSX.dmg and this gives me a 404 I was not able to test it with the latest Test version release.

It looks like this Problem is spcific to the iMac as I was not able to reproduce it on MacBooks.
