lttng-tracing-root-cause-analysis
lttng-tracing-root-cause-analysis is a Runtime diagnostics & profiling skill for AI agents, published by isc-projects in the bind9 repository on GitHub. Skillspace rates lttng-tracing-root-cause-analysis D (68/100) and it passed the safety scan; the rating is based on static analysis only.
Methodology for root-causing hard concurrency / memory-ordering bugs (intermittent races, use-after-free, RCU/lock-free publish-order defects, "impossible" stale reads) with LTTng flight-recorder (snapshot) tracing — when static analysis, printf, and a debugger all fall short. Covers the snapshot+violation+abort setup, tracepoint instrumentation discipline (why tracepoints not printf), how to enrich a violation event so the trace is self-diagnosing, and the trace-reading patterns that crack these bugs (notably: a stale-after-write "paradox" is a happens-before gap, not a timing bug).
