Dear Team,
Our Final Builder Server Web Interface suddenly stopped to work and we are getting following error. It was working fine but when I scheduled 3 continous builds in the queue, the last 2 builds terminated and got failed after that it's showing the following error message. Kindly look into this and do needful asap. If you need any other details please let us know.
