<!-- Answer --> This issue is likely caused by the task result (~1GB JSON) exceeding the default **`task.result_size_limit`** (16MB by default), which corrupted/stuck the task in the TaskStore. Tasks in HugeGraph are stored as graph vertices internally (`~task` and `~taskresult` labels), and when the result is too large, it can fail during save and leave things in a broken state [[1]](https://github.com/apache/hugegraph/pull/827). **To recover**, try force-deleting the problematic task via REST API: ```bash DELETE http://${IP}:${PORT}/graphs/${GRAPH_NAME}/tasks/${TASK_ID}?force=true ``` Example: ```bash curl -X DELETE "http://${IP}:${PORT}/graphs/${GRAPH_NAME}/tasks/${TASK_ID}?force=true"; ``` If even this API call hangs/fails due to the InterruptedException, you may need to restart the HugeGraph server first, then immediately issue the delete before the stuck task causes issues again. **To prevent this in the future**, increase the task result size limit in your graph configuration file (e.g., `conf/graphs/hugegraph.properties`) [[2]](https://github.com/apache/hugegraph/blob/9126c80e414c073b60fc074361b211cfb409e0eb/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/config/CoreOptions.java#L285-L298): ```properties task.result_size_limit=1073741824 ``` However, storing 1GB results as task output is not ideal. Consider paginating your Gremlin queries (using `.range()` or `.limit()`) instead of retrieving all results at once. **If the REST API is completely unresponsive**, since tasks are stored as vertices in RocksDB, a last-resort option would be to directly clean up the backend data, though this is risky. A server restart should restore normal operation for other tasks once the stuck task is cleared. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fhugegraph).* --- Share context across your team and agents.
