Just to state the yet non-stated to make sure that matters are clear
(many people may easily be unaware of that):

a server being a 32bit OS should IN NO WAY result in I/O transfers
of a heavy-weight I/O software being limited to 32bit, too (well, ideally......).
That's what the difference between "64bit file I/O" and actual 64bit OS was
supposed to be for (the transition to "64bit file I/O" was made
quite a bit *before* actual 64bit OSes properly supporting 64bit *CPUs*
were commonplace).

IOW, this likely indicates that a 32bit type
(i.e., a type limited/adhering to system-width) is erroneously being used
somewhere within the transfer chain, rather than an actual 64bit type
(see various stdint.h implementations for specifics)
that's suitable for 64bit data transfers on a 32bit system as well.

So much for the theory - now as to whether SVN transfers
are supposed to qualify for "heavy-weight I/O"
(i.e. whether that is a valid sufficiently frequent use case on 32bit platforms),
that's obviously another matter ;)

GNU/Linux. It's not the software that's free, it's you.
