An "Insufficient Virtual Memory" Error when Running a Model

An "Insufficient Virtual Memory" Error when Running a Model

Issue

An "insufficient virtual memory" error occurs when I try to run a model.

Resolution

Some DLLs require more than 2GB of virtual memory to run. On 32-bit Windows (Vista, XP, or Server 2003), you need a special operating system configuration to ask for more than 2GB of virtual memory.

To enable this you have to do some system configuration. Here's a Microsoft Knowledge Base article on how to do this for XP and Server 2003:

Vista, of course, is different. You have to use the BCDEdit utility to do the same thing:

The change can be made in Windows 7 by opening a command window as an administrator (press Windows key, type cmd and right-click on Command Prompt). Type BCDEdit /set increaseuserva 3072 and hit Enter.
