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
