Yes, sort only has a maximum of 3 GB of virtual address space so
it will never be able to load the whole 11 GB file into memory.

You could either write your own sort program that doesn't need
to have the whole file loaded or you could use a 64 bit machine
with at least 11 GB of available virtual memory, probably the
double...
