I have seen the same thing on my 4.0.8 VBox running on 64-bit Windows7 on a quad-core Phenom II with Ubuntu and FreeBSD guests. It has frozen up several times during compute intensive operations, usually video transcoding. For this reason I suspect it is not FreeBSD specific. Has anyone seen reports on this elsewhere? It actually happening started on 4.0.6. Never saw it on 4.0.4, but it had MUCH more annoying issues. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
