Loki instances using memcached for caching may emit excessive warning or error logs when the configured`memcached_client` service port name does not match the actual Kubernetes service port. This does not cause a crash or failure, but it results in noisy logs and ineffective caching behavior.

Grafana Loki may emit errors when attempting to write to a Memcached backend that has run out of available memory. This results in dropped index or query cache entries, which can degrade query performance but does not interrupt ingestion.
