# Wonderware WindowViewer 2014R2 memory issues

Problem:
After Windowviewer runs for ~12hrs and the operator clicks to open a screen there is an error message that states WindowViewer is low on memory (exact message unknown)

Applied fixes:
1) Set Windows virtual memory to the same size as the physical memory plus 128 (16128) [System/Advanced system settings/Advanced/Performance-Settings/Advanced/Virtual Memory-Change]

2) Lowered Memory Limit for in-Memory Graphics from 70% to 30% in WindowViewer Properties through WindowMaker [Special-Configure-WindowViewer-Viewer Memory]

12/24/24
Problem happening again.
All previous settings are still in place
Disabled High Priority Window Caching in WindowViewer properties (see 2 above)
