How Do I Know If I Need More Swap Space?

Use the swap –l command to determine if your system needs more swap space.

For example, the following swap –l output shows that this system's swap space is almost entirely consumed or at 100% allocation.

$ swap -l
swapfile                   dev    swaplo   blocks     free
/dev/zvol/dsk/rpool/swap  182,2       16   67108848     92

When a system's swap space is at 100% allocation, an application's memory pages become temporarily locked. Application errors might not occur, but system performance will likely suffer.
