.. or could be "not enough" so the pagedaemon is running and you are paging out, .. or could be due to other things making you wait for memory. My x250 works here, but I also have more memory. having a look at what's waiting in ddb if you can drop to ddb while it is hanging is often helpful. Additionally you can often see things if you are running top -S -s 0.1 in a window and watching it.
