Troubleshooting Exceptions: System.ServiceModel.ServerTooBusyException
A ServerTooBusyException exception is thrown when a server is too busy to accept a message.
This exception derives from the CommunicationException that represents a class of recoverable errors that might be thrown during communication between endpoints. Robust client and service Windows Communication Foundation (WCF) applications are expected to handle these exceptions. To prevent a handler for CommunicationException from catching the more specific ServerTooBusyException, catch this exception prior to handling CommunicationException.
