Johnathon - the "memory" line refer to the PseudoSwap feature of the HP-UX, which is by default
enabled and is from my point of view of little use, unless you don't have enough physical disks to create a sufficiently big disk swap area space. Anyway check the last line in "swapinfo -t", if that "PCT USED" get close to 100% than you're in big troubles since you don't have anymore virtual mem to use. For the 'maxswapchunks' set it to the maximum allowed (16384) and then forget about it.
