Permanent fails with StackHash on Windows Server 2008 x64
Hello. My host OS is Windows Server 2008 R2 Enterprise x64, guest OS is Ubuntu 8.04.4 LTS amd64. VM has 8 processors, 8GB RAM. Almost every time I start parallel build of something heavy (for example, Qt, Boost) VM gets stuck and/or VirtualBox faces APPCRASH. CrashedApplication always is VirtualBox.exe; CrashedModule was vboxdd.dll when VM network adapter was Bridged, after some googling I've changed it to NAT and now CrashedModule is StackHash.
I often have htop running on VM, and I've noticed that before crash there are some processes that use 100% of kernel time; if I have enough time to kill those processes, crash doesn't occur.
When I was building Boost, VM has crashed over 10 times while I was trying to build it with make -j8 and it has never been finished. However, when I tried to build it with make -j4, it has built in the first try.
Kernel version of Ubuntu is 2.6.24-26, I tried installing 3.8.0 - it changed nothing; GuestAdditions are installed. Also I tried downgrading to VirtualBox 4.2.4, it didn't help neither. I don't attach VBox.log because there is nothing about crash.
On the same host I have VM with fresh Gentoo, it has the same number of processors and I build that heavy software there too - it never crashed. What's the problem?
