Depending on how your APR (on the server) was compiled it may not be able
to handle files that are > 2GB. If you commit more than 2 GB at one time,
you will have a revision file in the fsfs repository that APR cannot
handle due to its size. I am not saying that is the problem, but that is
somewhere to start.

So my recommendation would be to go back to the idea of breaking the
import into chunks.

A lot of "seasoned" users try to avoid using svn import. An easy trick is
to perform a checkout of your empty repository into a local folder. This
then creates an empty working copy. You can then start creating your
folder/file structure that you want and use svn add and svn commit to get
it to the repository. This technique might make it easier for you to do
this in chunks.
