Out of memory errors if PAE (physical address extensions) enabled

Hello

I want to know if anyone else has this issue and how can be solved:
-We have a group of software applications, some developed with Ms.Visual
Basic 6.0 and some others with Ms.Visual Basic. NET 2003 (Framework 1.1).

-This software is working for years in different customers without
compatibility problems.

-But now happens this: we implemented the software on a Windows 2003 Server
Standard Edition 32 bits, 12 GB RAM, using the Physical Address Extension
(PAE) and randomly we get the error message "Out of memory" and "Stack out of
memory", either with the applications developed in VB6 or .NETs.

Without ever having played such an impact on our development environment or
other environments implanted to date, we have enabled this option on a
development server and we have managed to reproduce the issue, so that we
believe it may be some compatibility problem.

The second server is a clean Windows Server 2003 Standard edition 32 bits
SP2, no antivirus, up-to-date, no other software except our group of
applications and the Oracle 10 client so it can connect to the DB server.

Hello Antonio

You are using the wrong software with the wrong hardware

PAE can only be activated on
a.. Microsoft Windows Server 2003, Enterprise Edition (32-bit x86)
a.. Microsoft Windows Server 2003, Datacenter Edition (32-bit x86)
a.. Microsoft Windows 2000 Advanced Server
a.. Microsoft Windows 2000 Datacenter Server
So upgrade to one of these 32 bit systems or what i would personally do is
upgrade to a apropriate 64 bit operating system

The PAE switch will actually cost you memory to allocate the memory above
the 4 GB boundry so a 64 bit system is always a bether choice .
