vmstat displays cpu idle time at 100%

Since yesterday the vmstat command is displaying the cpu idle time at 100%At each time interval. It never changes. Not sure what it means other than it Quit calculating that stat. And I'm curious why. Using sar I can display a correctCpu idle percent, but vmstat does not. Any ideas why or suggestion to resolve.I was thinking a reboot might cure it, but it's a guess. Server has been up 83 days. We are running HP-UX B.11.11
