Reading/writing large files requires support from both the filesystem *and* the application. In you case it's almost certainly the application which needs to be fixed. See the following link for details of the changes you'd need to make in your code to get LFS to work. In your case, since the code works with large files on AIX it's probably just a matter of setting the neccessary flags when compiling you application. http://www.ece.utexas.edu/~luo/linux_lfs.html Hope this helps Simon.
