I have Windows Server 2008 and Sql 2005 SP2 installed on a new HP Proliant server with 2 logical driver. The first drive is raid 1+0 and the second is raid 5 with one online spare. I have MS Dynamics GP 10 SP 3 installed. When attempting to ugrade my GP 9 databases to 10, it lockes up the server and forces me to reboot without finishing the upgrade. The dynamics and system tables upgrade without error. It looks up when trying to upgrade the company tables. I have deleted and recreated the array and reinstalled the OS and Dynamics GP. I do notice that the private working set for sqlservr.exe continues to go up during the process. I have seen it reach 800,000K+ before it locks up. Not sure if that is normal or not. Any help would be great.
