1. A computer implemented method comprising:

controlling a data transaction processing system which maintains a data structure which stores data indicative of a state which characterizes the data transaction processing system, the data transaction processing system operative to automatically process electronic data transaction requests as they are received against previously received electronic data transaction requests, the processing of which results in at least one change to the data indicative of the state, the controlling further comprising:

determining, automatically by the processor based on a current state of the data transaction processing system, an extent to which a received electronic data transaction request can be processed by the data transaction processing system and thereby change the data indicative of the state of the data transaction processing system, and based on whether the received electronic data transaction request cannot be processed, can only be partially processed or can be entirely processed, assigning a comparison value;

identifying, by the processor, a first comparative value after an elapse of a first duration of time and a second comparative value after an elapse of a second duration of time subsequent to the first duration of time; and

determining, by the processor, whether a first difference between the assigned comparison value and the first comparative value deviates from a first threshold value, and where the first difference does not deviate from the first threshold value, determining, by the processor, that a second difference between the assigned comparison value and the second comparative value deviates from a second threshold value; and

halting, automatically by the processor, processing of electronic data transaction requests received by the data transaction processing system based on the determination that one of the first or second difference deviates from the first or second threshold values so as to prevent a subsequent change in the data indicative of the state of the data transaction processing system caused by processing subsequently received electronic data transaction requests.
