Doesn't "0" mean that it should NOT be running, or is that only if the minimum AND maximum are zero?
The latter, or if min=0 and max=-1.
The min and max define the permitted range, and are inclusive (a value of exactly the min or the max is permitted).
min max -> meaning, "display text" 0 -1 -> must have exactly 0 running, "found X, req. none" 1 -1 -> must have 1 or more running, "found X, req. 1 or more" 0 0 -> must have exactly 0 running (ie, not running), "found X, req. at most 0" 0 1 -> must have zero or one instances, "found X, req. at most 1" 1 1 -> must have exactly 1 running, "found X, req. between 1 and 1" 0 3 -> must have no more than 3 running, but can have as few as zero, "found X, req. at most 3"
As Larry said, -1 is only special when it is a maximum.
