All these problems can be reflected in software traces showing sudden gaps in threads of activity. I call this pattern Discontinuity per analogy with continuous and discontinuous functions in mathematics. Here is an example I came upon recently and it will be covered fully in the forthcoming pattern cooperation case study spanning both memory dump and trace analysis. One process was reported to have a long period of CPU spiking calculation and a CDF trace was recorded. When we open it we would see this periodic error: [...] […] Sometimes there are reported delays in application startup, session initialization, long response times and simply the absence of response.
