Troubleshooting Qlik Engine "Internal Inconsistency Type B" Error

[Sonja_Bauernfeind]

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

Server aborted. Reason for restart: Internal inconsistency, type B

The engine throws a general exception for internal inconsistency type B when it fails to release memory that has not previously been allocated, which commonly is a side-effect of a failure (access violation) and the subsequent clean-up.
