Excessive Sitting Regen

[DrivingZiggy]

So, this truck has never had a sitting regen. Never. Until a couple of days ago. Driver said she got the message on the screen and had to stop and regen twice.

Does this mean the DPF is at the point where it needs to be cleaned? What if I went all milk money on it? And if I finally get off my dead a$$ and milk money this b!tch, won't the DPF eventually fill up with soot?
