我在日志中遇到异常，与orientdb（2.2.19）相关

SYS_ERR: java.lang.IllegalStateException: Pool is closed

代码主要执行在orientdb中添加数据，在获取OrientGraphFactory.getTx（）调用时，我看到所有这些异常。

我正在调用commit（）调用，然后执行shutdown（）

private void commitGraph(OrientBaseGraph graph){
        try{
            graph.commit();
        }catch(Exception e){
        e.printStackTrace();
        }finally{
            graph.shutdown();
        }
    }

此外，在执行提交

时，NPE之后会出现这些异常

java.lang.NullPointerException
        at com.tinkerpop.blueprints.impls.orient.OrientBaseGraph.makeActive(OrientBaseGraph.java:362)
        at com.tinkerpop.blueprints.impls.orient.OrientTransactionalGraph.commit(OrientTransactionalGraph.java:177)

OrientGraphFactory初始化如下

factory = new OrientGraphFactory(url, userName, password).setupPool(1,50);

任何指针，抛出此错误的时间和原因都会有所帮助。

修改

我的orientdb-server-config.xml中的配置如下：

 <parameters>
                <parameter value="true" name="enabled"/>
                <parameter value="50" name="graph.pool.max"/>
            </parameters>

我可以看到，没有到达具有orientdb安装的远程服务器有很多例外。它与它有关吗？我可以看到以下异常

com.orientechnologies.orient.core.exception.OStorageException: Cannot create a connection to remote server address(es)

在getTx（）调用期间获取“java.lang.IllegalStateException：Pool is closed”异常
