Swap Space

Solaris 8 supports the concept of virtual memory by using space on a hard disk to temporarily store the contents of memory not currently being used. When the contents are needed, the system swaps out some other area of memory to the swap file, and then swaps in the requested contents.

As long as sufficient memory is available, swap space is not used. When the load on the system increases and resources (mainly memory) are in high demand, swapping may begin to occur.

Keep in mind that pseudo file systems (such as the /tmp TMPFS instance) use memory. As more /tmp space is used, the system will be forced to make more use of the swap space. Heavy use of the /tmp TMPFS instance could cause the system to run out of swap space.
