It happens with 2.2 crossing the 4GiB range, but not related to what he's seeing.

Other possible contributors:
o Squatter indexes (my estimation is that they add 50%)
o Directory sizes themselves
o Other cyrus.* metadata
You can use something like this to calculate just the total (sorry, you need GNU
du, find and xargs):
find `mbpath user.user1` -type f -name \*. -print0 \
|xargs -0 du -cm|awk '/total/ { tot=tot+$1 } END { print tot "MiB" }'
You need the awk if there are more files than possible for a single invocation
of "du". And you can calculate the metadata overhead by negating the "-name"
parameter:
find `mbpath user.user1` -type f \! -name \*. -print0 \
|xargs -0 du -cm|awk '/total/ { tot=tot+$1 } END { print tot "MiB" }'
