| prequel-2025-0096 Medium Impact: 7/10 Mitigation: 6/10 | Loki Ingester Memcache Object Size Limit Exceeded | Loki ingester encounters "object too large for cache" errors when attempting to store log entries exceeding memcache's configured size limit (typically 1MB). Large log lines remain in the ingester buffer causing continuous failed ingest attempts, pod health degradation, and eventual recycling. The accumulation of oversized entries can lead to buffer exhaustion and ingester instability. | Observability Problems | ingester | LokiIngesterMemcachedObject Size LimitCacheStorageObservabilityTelemetryThreshold ExceededData LossConfiguration |

When this occurs, cache writes fail and can lead to degraded ingestion performance, retries, and increased memory pressure on the ingester. | Observability Problems | ingester | LokiIngesterMemcachedStorageCacheMemoryData LossThreshold ExceededObservabilityConfiguration |
