Aias00 opened a new issue, #6744: URL: https://github.com/apache/shenyu/issues/6744
- severity: Medium - files: `shenyu-protocol/shenyu-protocol-mqtt/src/main/java/org/apache/shenyu/protocol/mqtt/MqttTransportHandler.java:42-44`; `MqttTransportServerInitializer.java:44` - description: `MqttTransportServerInitializer` registers `handler` as a `GenericFutureListener` on `ch.closeFuture()`, but `MqttTransportHandler.operationComplete(Future)` has an empty body. Cleanup of `ChannelRepository`/`SubscribeRepository` only happens via explicit `DISCONNECT`. A client that drops TCP without DISCONNECT leaves its `Channel` and subscriptions registered forever. - impact: Channel and subscription maps grow unbounded across disconnecting clients; future `send()`s try to write to closed channels. - suggested_fix: In `operationComplete`, remove the closing channel from `ChannelRepository` and `SubscribeRepository`. - confidence: High - related_existing: none --- _Identified during the 2026-08-02 deep re-scan; full list in [`docs/scan2-2026-08-02/06-medium-tiers.md`](docs/scan2-2026-08-02/06-medium-tiers.md)._ -- This is an automated message from the Apache Git Service.
