16180	windows host crashes when memory is full	gggeek		"I have recently started to get windows BSODs when the guest VMs are trying to allocate too much memory.

I am running Win 8.1 64bit on a laptop with 16GB of RAM, and have 2 VMs open at the same time with 8GB of memory set to each, so there is obviously some over-provisioning going one.
This works fine until some heavy-duty operation starts in one of the VMs. What happens then is:
- windows slows down to a crawl - I can see screen and cursor refreshes
- I can briefly see the 'vm has been suspended because of lack of memory' dialog box popping up
- the win BSOD kicks in

This did not happen until recently (version 5.1.8) at the moment, but it might be simply due to the fact that I was not using intensively 2 VMs with memory over-provisioning before.

The windows event log says:

L’ordinateur a redémarré après une vérification d’erreur. La vérification d’erreur était : 0x0000007e (0xffffffffc0000005, 0xfffff8015d657f50, 0xffffd0005c195d78, 0xffffd0005c195580)

The guest OS is dDebian 8.6

Note that the VM additions inside the VMs might not correspond exactly to the version of VBox running."	defect	new	other	VirtualBox 5.1.8				Linux	Windows
