Please verify first that it also happens with a supported host (Linux,
Windows, Mac) and then report it upstream at VirtualBox or probalby in
that case better DragonflyBSD.

Those problems are hard to find and usually can only be fixed if a
developer can reproduce it. I have also seen a 100% cpu problem recently
but as a workaround it helped to pause the VM and resume it after
restarting virtualbox. You could check VBox.log or any debug logfiles if
they have reported anything abnormal.

During the call for testers we recommend to always build with DEBUG
option enabled to spot all errors but in some cases that triggers
assertions that are uncritical and sometimes even bugs in the debug code
paths. So if you see a Segmentation fault please send us a stacktrace
from the core file (already described somewhere in the thread how to get
a core file and stacktrace) so that someone can check that.
