Sagging springs

[T3hk1w1]

I just crawled under the Heep to check the angle of the rear spring shackles, and noticed something funny about the springs. Took a closer look, and this is what I saw:

Obviously the springs are suppose to arc in the OTHER direction, and I'm wondering how immediate of a problem this is. Do I have to worry about a catastrophic failure; i.e. the main leaf breaking while I'm on a trail, or worse yet going down the highway, or will it just continue to sag more over time?

EDIT: I'm running stock height w/ original springs, rolling 235/75/R15s
