this would be my test #1

In theory, a misconfigured graph can do this. Munin can draw many
different types of graph, including cumulative values. Even for a data
type like this which is X events per unit time, if you tell munin to add
them all up, it will do so and graph it.
Qucik test is to look at the graph config.
