> a) could not reliably capture a one minute flame graph covering the issue, as the onset of it kept fluctuating; b) capturing a two or three minute flamegraph didn’t help either, and the issue was “drowned” in the normal workload profile. Vadim asked me for help. One interesting thing here is also the statistical nature of this problem: i.e. there are spikes but their duration are not exact or known when to start. Here[1] is some reference work done on Neural Spike Trains that seems relevant.
