This is confusing to me as I never see such behavior... Just for kicks, I
just loaded up two long pieces of DNA duplex (both not centered at the
origin) and tried solvateoct unit TIP3PBOX 5.0 iso and also 5.0 0.78 and
the molecules are completely surrounded with water as expected (with a
minimum of 5A layer of water around the DNA). Note that if the system is
large, the PDB format can be blown so that not all the waters are visible.
How are you visualizing the solvation? What version of LEaP/AMBER?
