Louise Robbins bought shares in an exchange-traded fund last Friday afternoon as markets fell, knowing that she had enough money in her Vanguard Group settlement fund to pay for the trade.

A Vanguard spokesman confirmed that other retail clients received similar messages and the problem would be resolved without customers having to take any action.
