I have a workflow that routes a list item for approval to 3 different levels. On the 3rd level the workflow keeps getting suspended with the below error message and I cannot figure out why as it does not happen every time. I have about 10 items that it keeps happening on and I have been able to get 9 of them to go through by terminating the workflow and starting it over from the beginning but 1 continues to fail. (It took multiple attempts to get the others to go through.)
