'pstat -s' will give you current swap usage information. I suspect that your swap partition isn't in /etc/fstab correctly and thus have no swap at all. With the merged VM/buffer cache, the system can periodically page out a page or two (but generally rare). If it tried to page just one page without swap, this would be obviously deadly. Free memory can be seen with 'vmstat -s'. The "free" plus "VM cache" pages are the total amount of 'free' memory. The system will try to use all of this otherwise unused memory for file caching. >If it is using the swap space, is there a way to force to use the ram >before the swap? It generally already does that. -DG
