Well, this failure is reliable. It happens after several days running. A highly compute-bound application running under Windows Codename "Longhorn" Server running under the latest Microsoft Virtual PC running under Microsoft Windows Vista RTM stops working. A dialog box openz to inform the operator and suggests "a solution" may be available. A big button labeled Close program is the ONLY choice. The Event Log suggests an illegal instruction has been tried and found wanting. So, is the bug in Virtual PC or does the problem lie elsewhere?Also, is there a better place to report what appears to be a solid, bona fide, REPRODUCEABLE, no argument BUG?SCREEN SHOTSee the dialog box and application that failed in the screen shot at the location above.

Hi , this error could be any of many reasons. Basically it is what earlier was known as Doctor Watson that reports that you application as either done something not allowed or it has hit a bug in Windows Server 2008 or it is having issues with hardware or it is not compatible with the new way that Windows handles memory where a program could get memory pages with different address. It thinks it will find its memory pages at x but windows has decided to use address y instead to better use the available memory. So in short, I would first try this on a non VM machine , maybe do some investigation with Sysinternal tools if you know how to use them and then file a bug. http://www.microsoft.com/technet/sysinternals/default.mspx Brjann
