It's not thirst, it's efficient usage. You weren't using it for
something else, were you?

If you were planning on using it later, well -- you can tell zfs
at boot time to never user more than X MB/GB in the ARC.

/etc/modprobe.d/zfs.conf
# reserve this much
options zfs zfs_arc_min=536870912
# don't grow past this, even if it looks ok
options zfs zfs_arc_max=8589934592
