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

Tue Nov 8 21:23:39 UTC 2011

That's cool, I just wanted to confirm that I was understanding … thx …

I'm about to bring online a 8.x system, so am not going to concern myself too much until I finish the upgrade, just figured I'd check to see if there was anything obvious with 7.x …

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.
