It handles these for us.

You are probably running out of address space. Look at how much memory
is being used in taskmanager. In 32 bit windows the default address
space is 2GB of that 2GB the largest memory block is about 1.2GB. The
reason why 1.2GB is the maximum block is caused by memory
fragmentation caused by windows dlls loading inside of this 2GB
address space. You can extend the address space limit to 3GB by using
the /3GB boot.ini switch and linking your application with
LARGEADDRESSAWARE.
