Engine service on Qlik Sense or QlikView restarts unexpectedly and intermittently, with a logged engine error message like;

Reason for restart: Internal inconsistency, type D

The engine throws this general exception when it fails with the deletion of dynamic arrays, TDynArray and TObjArray, which are used to store data sets during run-time.
