Even if you put more in it, the 32-bit address space limit will be
the limiting factor.

You almost certainly need a 64-bit machine. Even with the latest
xfs_repair, you need about 2GB of RAM for the free space checking on
a 14TB filesystem.
Try running:
# xfs_repair -m 1 -vv <device>
And it will tell you how much memory you need to repair the
filesystem. Note that this is only a rough estimate - it may be
quite a bit more than the amount specified depending on the state
and contents of the filesystem...
Cheers,
Dave.
