**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** The reported issue has been verified against the current codebase. **Root Cause:** When running with `--enable-proxy` (local/embedded mode), the `mqbroker` startup script embeds a full `BrokerController` inside the Proxy process. The `broker.conf` values are loaded into the standalone broker's config objects, but the embedded broker's `MessageStoreConfig` instance is not fully initialized from `broker.conf` — so `fileReservedTime` remains at its default value of `72`. When `mqadmin getBrokerConfig` is executed, it hits `AdminBrokerProcessor.getBrokerConfig()` → `Configuration.getAllConfigsInternal()`, which re-merges the live config-object properties back into the cached `allConfigs` map. Since the embedded `MessageStoreConfig.fileReservedTime` is `72` at runtime, the merge overwrites the cached `168` from `broker.conf`, producing the log line: ``` Replace, key: fileReservedTime, value: 168 -> 72 ``` **Impact:** The displayed config value diverges from what was configured. The actual file retention behavior depends on which config object the store layer reads at runtime — but the config drift itself is a correctness issue. **Severity:** Medium — affects observability and may cause confusion; actual file retention depends on which config path the CommitLog deletion logic uses. **Key files involved:** - `broker/src/main/java/org/apache/rocketmq/broker/processor/AdminBrokerProcessor.java` (`getBrokerConfig` handler) - `remoting/src/main/java/org/apache/rocketmq/remoting/Configuration.java` (`getAllConfigsInternal`, `merge`) - `broker/src/main/java/org/apache/rocketmq/broker/BrokerController.java` (embedded broker wiring) - `store/src/main/java/org/apache/rocketmq/store/config/MessageStoreConfig.java` (default `fileReservedTime = 72`) **Note:** The Proxy module itself does not write or trigger config updates. The issue is in how the embedded `BrokerController` is initialized in `--enable-proxy` local mode. An automated fix proposal can be generated if the community confirms the approach.
