Yes. Use less memory.

Look over your program where you are needlessly wasting memory. Maybe you are reading a complete file into memory instead of processing it line by line. Maybe you are doing something else that wastes memory.

Even still, 125000 lines is not much, so most likely you are doing something that wastes a lot of memory.
