Are you referring to clumping coffee as it exits the chute/doser? This tends to happen at various times during the year based on humidity for me, what I do is use something to break up the clumps and even out the distribution. Some folks use a the chopstick and portafilter funnel method, I use a stainless surgical probe and break it up as I dose.

I second the above. I would guess that it may be more the time of year or the weather than it is the grinder. It never hurts to change the burrs if they have some time on them as they are pretty inexpensive and you will then have a known starting point. If however, you bought the grinder new then unless you are a coffee shop, I doubt that you have much wear on them.
I ran my SJ (s) on a timer and dosed by time rather than using the doser or weighing the beans. A timer that reads to 1/10 second is pretty consistent in shot volume when you use the Mazzer hopper and keep a constant volume of beans so the pressure on the beans/burrs is consistent.
I also used a plastic chop stick (wood would work just fine too) to clean the chute between the grind chamber and the doser. This requires removing the safety guard or if it is an automatic grinder, the top switch and guard need to go so it is then a manual machine.
In short though, for the most part, clumps happen. Grinders with dosers tend to drop fewer clumps into the PortaFilter as the vanes in the doser tend to break them up. DoserLESS grinders tend to clump more and may require work in the PF after dosing but if you are a shop, that is an extra step that will cost time for each and every shot you pull.
