VirtualBox 4.0.12 + FreeBSD 7.4-STABLE causes server hangs ...

[Hub- FreeBSD]

Doesn't that sort of defeat the purpose of virtualization if the virtualized environment can still blow up the host system? :)

But … reading your note below, did this cause issues with your host OS (either a crash or hang?), or did it just cause problems within the guest OS, or the ability to start it up?

I also had the same issue with my FreeBSD VM and reinstalled that as a version 9 system and have no issues since.  I hadn't been maintaining those as well so I can't say when or why it broke and didn't lose much.
