swap(1M) - swap administrative interface (man pages section 1M: System Administration Commands) - Sun Microsystems

tells you:

Quote:

swap -s

Print summary information about total swap space usage and availability:

allocated: The total amount of swap space in bytes currently allocated for use as backing store.

reserved: The total amount of swap space in bytes not currently allocated, but claimed by memory mappings for possible future use.

used: The total amount of swap space in bytes that is either allocated or reserved.

available: The total swap space in bytes that is currently available for future reservation and allocation.

These numbers include swap space from all configured swap areas as listed by the -l option, as well swap space in the form of physical memory.

So, you see that /tmp is almost empty but your memory is being thoroughly utilised, and hence the alerts.
