Looks like the Solaris 10 version of prstat doesn't show swap reservations.

Try this dtrace script:

swapinfo.d

Something is definitely reserving swap space, the question is what. What does "prstat -s size" show? Then you can use "pmap" on the big ones and hopefully find which one(s) are mapping a lot of anonymous memory.

Another possibility are shared memory segments. There are ways to create those that don't use any swap space because they get locked into memory. I know DISM segments do use swap because those aren't locked into memory like plain ISM segments.

And FWIW, if you do "uname -a" you'll see "SunOS ... 5.10 ...". Solaris replaced SunOS 4.x, so it's SunOS 5.x. Solaris 8 would be SunOS 5.8. Solaris 11 is SunOS 5.11.

Looking at this data again... Should more swap be added? Is this telling me that only 7761 MB of swap exists?
