Help with " guru meditation error"

[ben2008]

Hi. I have a problem with my VM. When ,for example, i try to attach files in gmail, my VM stop and this error appear: "Guru Meditation - critical error - VirtualBox the machine....."
My vM works normally, but when i try to upload a file, my mv fail.
I've uninstalled the updates, cos i thought that could be the problem. But i got the same.
I've attached the VBox.log file to provide additional information.

Thanks.

MV: Win Server 2003
Oracle: SQL server 2005
VBox: 4.2.0

There is no "guru meditation" recorded in the provided log. Also, the log file is truncated - which is not a consequence of having a guru meditation. It's usually a consequence of grabbing the log for a VM that's still running. And please clarify that this crash is coming from VirtualBox on your host? A picture might be nice.

I will note however that the ".0" release of any development branch is also by definition the buggiest - there have been 13 maintenance releases of 4.2.x since then. If you want to stick with the 4.2.x branch then I suggest that you upgrade to 4.2.24 (not 4.2.26 as that has introduced new problems).

I also note that you have a dual core CPU and you're assigning both cores to the VM. This isn't recommended - it leaves the host starved of resources, which can cause performance problems. It shouldn't cause a crash however.

I'm afraid I can't see what that image is supposed to tell me. Please explain its relevance. I've ignored the new log, since VirtualBox logs are useless for diagnosing guest application errors. However I can see that it still says 4.2.0.
