Does anyone know if there is an x64 version of hotfix 894472? The 32-bit
version is only available by special request (or from the Stata Corp.
website, where it lives with MS permission), and I can't get a clear answer
from Microsoft about the existence of a 64-bit version.
On 32-bit XP this hotfix, 894472, repairs the memory allocation error
induced by SP2 that causes a specific DLL (Xpsp2res.dll) to load in the
middle of memory, at 0x20000000 (this info is according to the MS support web
page for 894472). This location for the DLL fragments the memory space, and
prevents software that needs a large block of contiguous memory from being
allocated the memory it requires.
I use a stats package called Stata, which keeps all data in memory at once,
and I am working with multi-GB data files. On 32-bit XP I needed to run this
hotfix to move from 900MB to about 1.4GB in available RAM for Stata (which
hasn't been enough for quite a while). So I have upgraded to X64 on
workstation class PC's.
Until recently there was not a version of SP2 for X64, so I was in fine
shape. However, Stata Corp says this problem now also hits X64, once you
apply SP2 (which I just did for security reasons). They insist there is an
X64 version of the hotfix, and that it needs to be run on XP X64 after SP2 is
installed.
So far, even after SP2 I seem to get all the memory allocated to my Stata
sessions that I need, so I cannot actually verify that I have a problem. But
I am not clear how much of my session memory is coming from virtual RAM, and
in any event I am worried there either is, or will be at some point, a
problem with getting access to enough real RAM for Stata.
So far, I cannot find out any further information from Microsoft, although
my University has a big site license, and I have our support folks trying to
find out.
Anybody have any ideas?
Thanks.
