Before understanding the cap violations let check out the cap definitions
The capacitance on a node is a combination of the fan-out of the output pin and the capacitance of the net. This check ensures that the device does not drive more capacitance than the device is characterized for.
The violation can be removed by increasing the drive strength of the book
By buffering the some of the fan-out paths to reduce the capacitance seen by the output pin.
