I don't think that's true, even before chuncked uploads.
Note that this is from (quite) a while back, but what I had noticed (back
then) is that your upload location (usually /tmp) should have enough HDD space
to store the whole file.
I noticed it when running it in (VBox) virtual machine with only 512MB RAM
allocated and therefor /tmp was also rather small as Debian allocated (by
default) 20% of the size of your RAM for /tmp.
You can of course change that by modifying /etc/fstab.

Without any activity (and I'm the only user anyway) my 'free -h' stats are:
diederik@cknowsvr01:~$ free -h
total used free shared buffers cached
Mem: 3.9G 247M 3.6G 17M 20M 110M
-/+ buffers/cache: 116M 3.8G
Swap: 4.1G 0B 4.1G
And with me logged in to the web interface:
Mem: 3.9G 409M 3.5G 25M 23M 232M
-/+ buffers/cache: 153M 3.7G
Swap: 4.1G 0B 4.1G
Note that I have very few files etc stored in my/this owncloud instance.
As you can see that is significantly lower then you have and there are a couple
of more services running on that machine (Debian testing, OC 6.0.1+dfsg-1).
So I recommend 'tearing up' your machine piece by piece to find what's causing
your memory usage. And by 'tearing up', I mean virtualized vs non-virtualized,
with NFS and without, SAN vs local disk and synching and no synching.
It would probably also be informative to have (h)top and iotop running while
performing those tests.
HTH,
