[QGIS-Developer] [Qgis-user] Qgis crashes while loading WMTS layers

[Patrick Dunford]

Hi

In reply to your comments

There are a few different questions but Gimp wouldn't be able to write 
its temp file into the swap area because only the operating ssystem 
itself would be able to access that. Gimp has the ability to use virtual 
memory and a separate temporary area. If you configure a tile cache and 
it runs out of physical RAM then the tile cache is pushed into swap 
exactly as one would have thought.

Cheers
