| prequel-2025-0072 Low Impact: 3/10 Mitigation: 2/10 | OTel Collector Dropped Data to to High Memory Usage | The OpenTelemetry Collector’s **memory_limiter** processor (added by default in most distro Helm charts) protects the process RSS by monitoring the Go heap and rejecting exports once the *soft limit* (default 85 % of container/VM memory) is exceeded. After a queue/exporter exhausts its retry budget you’ll see log records such as: ``` no more retries left: rpc error: code = Unavailable desc = data refused due to high memory usage ``` The batches being dropped can be traces, metrics, or logs, depending on which pipeline hit the limit. | OTEL Problems | otel-collector | OTELMemoryBackpressure |
