Missed pages going from Yellow to Red

[Pat Vaughan]

This morning I had a filesystem start to fill up and go to a yellow state.
 Hobbit sent the Email as expected.  But then the alarm went to a red
state. Once it goes to a red state, I should get a page.

At first I thought it might be something to do with the long REPEAT time
on this rule, but it looks like there is only a problem when the state is
yellow and then switches to red.

Has anyone else noticed similar behavior?
