Yes, a strange problem. I can't recreate it here.

Almost a 2x factor of difference. I have to ask, might part of your
data under /var be mounted on a different filesystem?

Huh? Did you miss something when posting that command? It seems only
half constructed.
I tried a similar experiment on my system. Here is my result.
du -sb /var
329510912 /var
sum=0; for f in $(find /var -print0 | xargs -r0 ls -ld | awk '{print$5}');do
sum=$(expr $sum + $f); done ; echo $sum
328859152
find /var -printf "\n" | wc -l
6460
Since du really reports in block size as reported by the filesystem
some difference would be expected. This is typically a 512 byte chunk
on classic filesystems but will be different on newer filesystems.
Also, optimizations of storing data in the inode itself, etc. The
above result was on ext2.
Your result seems really unaccountable. I can't explain it. If it
would be possible for you to help by debugging in the code it would be
much appreciated.
