Issue

When you’re working in Tableau Desktop, the following warning appears:

Tableau is low on process memory and may be forced to abruptly exit. Please save your work.

Environment

Tableau Desktop

Resolution

Troubleshooting steps include any of the following tasks:

  • Decrease the number of worksheets in the workbook.
  • Reduce the number of additional applications that are running on the computer.
  • Use Tableau Desktop on a 64-bit computer. (See Additional Information below.)
  • Upgrade to the 64-bit version of Tableau Desktop.

Cause

Windows does not have enough contiguous blocks of memory available.

Additional Information

In 32-bit Windows systems, programs can access 2GB of virtual address space (process memory), or up to 3GB when the /3GB switch is used during system startup.

Tableau Desktop is a 32-bit, Large Address Aware application. In 64-bit Windows systems, such applications can access the maximum 4GB of virtual address space allowed per 32-bit process.

For more information, see the section “Comparison of memory and CPU limits in the 32-bit and 64-bit versions of Windows” in the Microsoft Knowledge Base article How to determine the appropriate page file size for 64-bit versions of Windows.
