To prove to yourself that your filesystem supports files larger than 2G,
do the following:

# cd <directory where you have problems>
# dd if=/dev/zero of=foo.bar bs=1000K count=3000
# ls -lh foo.bar

Now that you've seen that your log file could be larger than 2GB with
a well-written application, it's time to have another look at the
application itself and see why it's breaking.

That's interesting...  perhaps the application libraries are
different?  Dunno, I'm not a programmer and have never run debian before
either.
