Just remember that by default lsof prints only first 9 characters of process name, so processes with long names will be cut. You can change how much initial characters lsof prints with +c command, but often kernel does not supply full names for lsof, example limit in my box is 15 characters

>lsof +c 64

lsof: +c 64 > what system provides (15)

So

lsof +c 15 is maximum
