I am intermittently receiving the following error on two different API Projects. The API Projects have been functioning normally for nearly a year without change. When the error starts occurring it happens in bursts lasting several minutes, then starts functioning properly again. The error events happen several times an hour, we noticed the errors happening early last night more than 12+ hours ago. Any help is appreciated.
