[Gimp-developer] Temp file stops at 2GB

[Michael <mike@xxxxxxxxxxx>]

I have compiled Gimp 1.2.3 with -D_LARGEFILE_SOURCE 
-D_FILE_OFFSET_BITS=64 and it can see files over 2GB ok, but if I create 
a new image that is over say 3GB then the swap file fills up until gets 
to 2GB and then stops. Gimp then starts to use up the rest of physical 
memory until the kernel jumps in and then sends it to its rest.
Is there a variable in the source that I can increase to make the swap 
file bigger?
