ColdfirexAnybody ever seen a VM GSOD from enabling VSS with BUDR?
email@example.comThis is purely my opinion, so take it with a grain of salt....
I have seen many image based backup solutions (including Acronis and BESR) suffer from the GSOD. My opinion is that this is not a bug in the backup products; the problem lies in the way that Windows Server 2003 utilizes virtual memory.
I make heavy use of both BESR and Acronis. I have some servers that experience this GSOD problem daily, and others that do not experience it at all. I would like to point out that I have not had a single GSOD under Windows 2008 (32 or 64-bit) or Windows 2003 64-bit. I believe the reason for this is that newer operating systems have access to a larger pool of virtual memory (paged, nonpaged, etc). Reference the following MSDN article:
If you look at the chart titled "Memory and Address Space Limits" you will notice that the virtual memory pool is fixed in older (non 64-bit) versions of Windows. Since many applications and drivers dip into this limited pool, the pool can become depleted. When there is no water left in the pool, then none of the kids can play. (None of your processes can function, including explorer.exe that renders the desktop that you see.)
