The HStore t `docker compose down` keeps named-volume data. `docker compose down -v` intentionally deletes it. +### Server logs and crash files + +Both Server images (`hugegraph/hugegraph` and `hugegraph/server`) write the HugeGraph log to container stdout. WARN and above from Hadoop, ZooKeeper, SOFA, Netty and Commons also reaches stdout; their INFO output, the audit log and the slow-query log stay in files only. Launcher errors that stop the Server before Java starts, such as an unsupported JDK or too little free memory, go to stderr as well as `hugegraph-server.log`, so when a Server exits during startup, `docker logs` or `kubectl logs --previous` shows why. Review Comment: 🧹 Blocking: no. Summary: This sentence implies ZooKeeper and SOFA INFO messages remain in files. Evidence: both `org.apache.zookeeper` and `com.alipay.sofa` are configured at WARN in `hugegraph-server/hugegraph-dist/src/assembly/static/conf/log4j2.xml:114-120`, so INFO events are discarded before either appender. Please limit the file-only INFO statement to the INFO-level Hadoop, Netty, and Commons loggers. -- This is an automated message from the Apache Git Service.
