<!-- Answer --> The errors in your `hugegraph-server.log` suggest issues with RocksDB lock files and potential misconfigurations during the startup of HugeGraph within Docker. Here's how to address these: 1. **Ensure Proper Shutdown**: Verify that the HugeGraph container was properly shut down to prevent RocksDB from being locked. Use `docker stop <container_id>` for a clean shutdown. 2. **Check Docker Logs**: Use `docker logs <container_id>` to look for specific error messages that can guide you to the root cause of the issue. 3. **Volume Permissions**: Make sure the Docker volume for HugeGraph has the correct permissions, as permission issues can prevent RocksDB from accessing its files. 4. **Configuration Review**: Double-check your HugeGraph configuration files, especially those related to RocksDB settings, to ensure they're correctly set up for Docker. 5. **Resource Allocation**: Ensure the Docker container has enough resources (memory and CPU) as RocksDB and HugeGraph can be resource-intensive. 6. **Docker and HugeGraph Versions Compatibility**: Using compatible versions of Docker and HugeGraph is crucial to avoid unexpected issues. If these steps don't resolve the issue, consider recreating the HugeGraph container or reaching out to the support community with detailed logs and configuration settings for further assistance. Additionally, the `java.util.concurrent.RejectedExecutionException` indicates the system's inability to handle more tasks due to exhausted work queues or resource limitations. Tuning the executor service configurations based on the expected workload and ensuring adequate system resources can mitigate this issue. The `HugeException: Failed to open schema transaction` error points to problems initializing or operating the schema transaction, possibly due to backend store issues or configuration errors. Ensuring backend store connectivity, reviewing configuration settings, and checking system resources are key steps to resolve this. If the problem persists, updating HugeGraph to the latest version or seeking help from the support community may be necessary. <!-- Dosu Comment Footer --> <details> <summary> #### Details </summary> **Sources** - [[Question] docker挂载数据目录时，启动失败](https://github.com/apache/incubator-hugegraph/issues/2298) - [重启HugeGraphServer超时，RocksDB不能被打开](https://github.com/apache/incubator-hugegraph/issues/367) - [Windows环境下运行hugegraph-master中的Example1时报错，rocksdb无法启动](https://github.com/apache/incubator-hugegraph/issues/690) - [hugegraph-server/hugegraph-dist/docker/README.md](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-dist/docker/README.md) - [content/en/docs/quickstart/hugegraph-server.md](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/en/docs/quickstart/hugegraph-server.md) - [hugegraph-store/hg-store-rocksdb/src/main/java/org/apache/hugegraph/rocksdb/access/RocksDBOptions.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-store/hg-store-rocksdb/src/main/java/org/apache/hugegraph/rocksdb/access/RocksDBOptions.java) - [content/en/docs/changelog/hugegraph-0.12.0-release-notes.md](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/en/docs/changelog/hugegraph-0.12.0-release-notes.md) - [content/cn/docs/changelog/hugegraph-0.12.0-release-notes.md](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/cn/docs/changelog/hugegraph-0.12.0-release-notes.md) - [hugegraph-store/hg-store-rocksdb/src/main/java/org/apache/hugegraph/rocksdb/access/RocksDBSession.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-store/hg-store-rocksdb/src/main/java/org/apache/hugegraph/rocksdb/access/RocksDBSession.java) - [hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/backend/store/raft/RaftContext.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/backend/store/raft/RaftContext.java) - [hugegraph-server/hugegraph-rocksdb/src/main/java/org/apache/hugegraph/backend/store/rocksdb/RocksDBOptions.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-rocksdb/src/main/java/org/apache/hugegraph/backend/store/rocksdb/RocksDBOptions.java) - [hugegraph-server/hugegraph-rocksdb/src/main/java/org/apache/hugegraph/backend/store/rocksdb/RocksDBStore.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-rocksdb/src/main/java/org/apache/hugegraph/backend/store/rocksdb/RocksDBStore.java) - [content/en/docs/guides/faq.md](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/en/docs/guides/faq.md) - [hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/StandardHugeGraph.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/StandardHugeGraph.java) - [hugegraph-server/Dockerfile](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/Dockerfile) <br/> **About Dosu** This response is meant to be useful and save you time.
