Sure. You are again confusing free and virtual memory. Swapping occurs when you are out of free physical memory. This isn't your case. You are out of unreserved virtual memory.

Also, "top" shows 8GB of swap as "free". and "swap -l" shows everything but 62MB as free. I'm assuming top and swap -l are showing similar values, but it's odd that both would show that swap is almost untouched.
Top isn't part of the OS so might just be wrong. I never use it on Solaris nor trust its statistics. I use prstat instead. In any case, reserved memory doesn't physically use any block on the swap area. It just reduces the size of memory available for new reservation.
