Erroneous states classification in dictributed computing systems and sources of their occurence

The paper defines the classes of erroneous states in distributed computing systems and sources of their occurrence. Some classes of these states are illustrated experimentally by inducing RabbitMQ abnormal behavior in the OpenStack software platform. The simulated erroneous states were observed actually in conditions close to the exhaustion of resources of the OpenStack software platform operation. To get erroneous states in the OpenStack platform, the RabbitMQ configuration file was tuned in order to simulate shortage of resources. The paper also contains the analysis of the incident, which occurred in the traditional information network infrastructures and can be treated as the implementation of the classes of erroneous states as well.
