The first two number of vmstat is running process and blocked process, the sum of the two number should equal to system load. But it's inconsistent in this case.
linux load average counts processes that are doing disk IO or network IO as being 'ready'. they aren't actually running, but neither are they waiting on user input ('blocked' per vmstat's version of reality).
If I'm not mistaken the "cost" of switching between processes also adds to system load...
