Again: hard hang of physical server

[bauer40]

Ooops, it did it again....

In five days of using VBox 3.1.2, I had two hard hangs of the physical server, effectively needing it to hardly power it off and on again using the power switch.

I run Debain, Solaris 10 and Windows XP guests on the physical server, which uses Solaris 10 u7 with KJP 141415-04.

It happend with and without Intel VT enabled.

Specialty: I make use of tagged vlan interfaces (e1000g4000, ...)

First, I discovered that the VM running my web proxy was no longer able to ping one (and only one) physical workstation in my network. Only the connection between the VM and the workstation was affected. The workstation could be pinged by other hosts on the net, and the proxy were able to ping others.

During the diagnosis of that behaviour, the physical server running VBox froze. I was not able to fall into the kernel debugger, and even the NumLock-LED did not change when pressing the appropriate key on the keyboard. It was a complete lock up.

It is acceptable for me to live with a few more hangs to diagnose the problem, if somebody is able to tell me how I can collect information which helps Sun to track down that problem.
