Why does my trim caulk keep cracking?
When caulking interior trim the caulk is usually wet wiped to remove the excess and to give a clean look.

Cracked grout is frequently the result of weak grout structure. The liquid in the grout mixture inevitably evaporates, as it was designed to do, but excessive evaporation can leave pinholes that will leave it vulnerable to cracking.
How do you know if caulking is bad?
If your caulk has not developed a skin, then it has most likely expired, which means that your caulk will not harden (cure) once you try to use it. You can also tell if your silicone caulk is expired by feeling the texture in the tube. If the caulk is hardened in the tube, then you won’t be able to use it.
How big a gap can you caulk?
Fill gaps up to 1/4 inch in width with caulk. If you have tile on the wall adjoining the tub, select a caulk that matches the color of the grout. If your gap is smaller than 1/8 inch in width, use regular caulk; fill gaps larger than 1/8 inch with a sanded caulk.

When you see walls – that looks like – that sounds like shrinkage.
