I think I understand. It looks like your system has a large amount of 
real memory, but a small amount of swap allocated. swap -l returns 100% 
used (and hence check_swap [-a]) because all the swap disk is filled. 
However /tmp, which uses a combination of real memory and swap, is 
returning lots of space, so your system is not really having any 
problems.

Weird how Solaris decides to use swap space before real memory, but 
maybe there is some setting to say fill up swap first.
