我打算用./neo4j-admin import --nodes Player.csv导入一个大一点文件，但是报错WARNING: Max 1024 open files allowed, minimum of 40000 recommended. See the Neo4j manual. WARNING! You are using an unsupported Java runtime.

Please use Oracle® Java™ 11, OpenJDK™ 11 to run Neo4j.

修改35行和36行，设置JVM初始堆内存和JVM最大堆内存 dbms.memory.heap.initial_size=2048m dbms.memory.heap.max_size=6144m 我的配置文件修改前面有#

#35到#46行如下：

dbms.memory.heap.initial_size=2048m dbms.memory.heap.max_size=6144m If Neo4j is running on a dedicated server, then it is generally recommended to leave about 2-4 gigabytes for the operating system, give the JVM enough heap to hold all your transaction state and query context, and then leave the rest for the page cache. Java Heap Size: by default the Java heap size is dynamically calculated based on available system resources. Uncomment these lines to set specific initial and maximum heap size. #dbms.memory.heap.initial_size=512m #dbms.memory.heap.max_size=512m

请大家帮助我解决，万分感谢！
