If I had to guess the stalled fermentor was the last to be filled and got less of the wort nutrients.

When splitting a single wort into two fermentations. It's important to alternate the filling of the vessels about 10-20% fill before alternating. This blends the wort, so each vessel gets a share of the nutrients that can drop in the cold break.

Edit: Possibly more oxygen than the other fermentor causing a longer growth / lag phase.
