Aias00 opened a new issue, #6840: URL: https://github.com/apache/shenyu/issues/6840
## Description `PolarisSyncDataService.doRemoveListener` removes the listener from the `ConfigFile` but does **not** remove the entry from `watchCache` (contrast `NacosSyncDataService.doRemoveListener:85` which calls `watchCache.remove(key)`). When `AbstractNodeDataSyncService.unCacheSelectorData/unCacheRuleData/etc` call `removeListener → doRemoveListener`, the stale entry remains. When the same key is re-created, `getServiceConfig` checks `watchCache.containsKey(key)` → true → returns null at `:77-78` without registering a new listener, so the re-created item is never watched/fetched. ## Location - `shenyu-sync-data-center/shenyu-sync-data-polaris/src/main/java/org/apache/shenyu/sync/data/polaris/PolarisSyncDataService.java:105-111` ## Impact After any delete+recreate of the same config key, the gateway misses the new data; routes stay stale/missing until full restart. ## Suggested fix Add `watchCache.remove(removeKey)` in `doRemoveListener`. ## Related existing None. -- This is an automated message from the Apache Git Service.
