Totally irrelevant.

Note where it says "File too large".

This file has crossed the magic 2.0 GB limit.  Things are going to start
breaking around it.  Apparently the version of SVN you're running thinks the
size of a file is a 32-bit SIGNED integer.  Other possibilities include a
limitation of your kernel or filesystem, but I'm inclined to suspect your
SVN build.  (The last filesystem limit I encountered was FAT32, and its
limit was 4.0 GB, not 2.0, and as for the kernel, I believe yours is of
sufficient new-ness to support 64-bit file offsets.)

You could try rebuilding your SVN with FILE_OFFSET_BITS=64... I'm not 100%
clear on what the officially-supported configure method is for this,
however.  Perhaps someone else can jump in...?
