> h2. Notable operational fixes
> h3. HDDS-15849 — XceiverClientGrpc.close() blocks under XceiverClientManager
> lock
> Impact: Graceful gRPC channel shutdown while holding the client manager cache
> lock can serialize concurrent client acquisition and cause severe performance
> degradation under load.

> Impact: Invalid characters in Ratis event metric names/labels can cause
> Prometheus scrape failures on JMX/Prometheus endpoints.

> Impact: Recon cluster capacity / Ozone used space did not match actual data
> written under freon workloads.
