In the first analysis pattern variant, insufficient memory may be reported because of full stack region and in the second analysis pattern variant, stack overflow is reported because there is not enough memory to expand stack region.
This duality can aid in new pattern discoveries and especially in analyzing possible root causes and their causal mechanisms software pathology given the multiplicity of diagnostic indicators when we consider parameters as analysis patterns themselves.
It is a common sequence when a memory leak fails memory allocation, and then certain pointers remain uninitialized or NULL. Consider its dual Insufficient Memory Invalid Pointer when, for example, memory is not released because some pointer becomes invalid.
The latter can happen when memory is overwritten with NULL values, or access violation is handled and ignored. It is usually a log or trace message. Usually, such messages are generated from specific code points, and, therefore, may have unique identifiers.
Such UIDs can be mapped to specific colors: For visualization purposes and 2D processing, we can collapse 1D picture into a 2D loxel image using top-to-down and left-to-right direction: We can also include Silent Messages in the picture by imposing fixed time resolution grid: We apply the same procedure to get 1D and 2D images: Each loxel may contain Message Invariant and variable parts such as Message Constants and other data values such as handles, pointers, Counter Values , and other Random Data in general.
We call a variable parts mexel, and mexels form layers in order of their appearance in loxels: Therefore, for this modeling example, after loxelation and mexelation, we got 3 layers that we can use for anomaly detection via digital image processing and machine learning: In conclusion, we would like to note that this is an artificial representation compared with the natural representation where trace memory content is used for pixel data.
The pictures missing in the first pattern descriptions were later added to the training course which initially served as a reference for the first 60 patterns: When more and more patterns were added to the pattern catalog, we published an updated reference , which is now in the second edition and covers more than patterns.
