Please predict whether this patent is acceptable.PATENT ABSTRACT: Aspects relate to a computer implemented method for detecting abnormal contention. The computer implemented method includes collecting resource modeling data for a serially reusable resource, wherein the resource modeling data includes one or more of request count data and contention data and storing, in a computer readable storage medium, the resource modeling data in an in-memory database. The method also includes creating and training a first model and a second model using the resource modeling data and one or more cognitive computing tasks and categorizing a contention event as an abnormal contention event using the first model and the second model.
