Obviously that guy does not have any problem on his 6500 box. Top shows the misleading information, as solaris always display the physical memory usage in the virtual memory usage.

another smaple here, I have totally no swap at all, but it shows 1109M swap in use. Actually 1109 is the physical memory usage, by oracle (900m) and other small applications and solaris itself.
