Hi John,
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.

two completely different sorts of numbers. vmstat is printing the %
of CPU usage by user, sys, and idle. load average is the average
number of 'ready to run' processes in the last 1, 5, and 15 minutes.
