On nodes with >300 cores, one interval's burst of per-hwthread metrics overran the fixed 200-slot channels. With blocking sends at every hop, sink back-pressure propagated to the collectors, the collection round exceeded the interval, and time.Ticker silently dropped the missed ticks - whole intervals were skipped without any log message. - multiChanTicker: deliver ticks non-blockingly and warn when a consumer misses a tick instead of stalling all consumers; guard the channel list with a mutex (data race with AddChannel) - collectorManager: run the collection round detached from the tick loop, skip-and-warn when a round is still running, log per-collector and per-round durations at debug level, close serial collectors on shutdown - metricRouter: buffer the interval timestamp channel and drain it before stamping, so metrics never carry the previous interval's timestamp; warn when the collector input channel is full at tick time - main: scale the inter-manager channels to max(200, 24*NumCPU), overridable with the new optional channel_buffer_size config option - add first unit tests for ticker, collector manager and router Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
