I suspect ocfs2 because when we run RMAN backup the free memory goes from 8 GB down to 200 MB. When I umount the ocfs2 backupdisk after the backup is finished, the memory is released again.

1.2.6 is about three years old. I would recommend you upgrade to
atleast 1.2.9.

Looking at the release logs, I do see a similar issue fixed in 1.2.7.

But I doubt you are hitting that issue as a leak in the kernel can only
be reclaimed by a reboot.
