This message will refer to the last box of the chain, to match the behavior of InDesign user interface, but it will also specify the ID of the first box in the chain. For example:
Text overflow in box 129 on page 7 of chained-text starting at box 64 of page 6
You can then refer to the templates manager to see the details of the parent box in which the current overflowing box is located.
Note that overflow is sometimes caused by the last end-of-line character. You can check that the present text overflow message is correct, using the InDesign preflight panel.
