OrientDB版本：3.0.5 Java版本：1.8 操作系统：Debian

你好

在执行以下简单代码时，我遇到了与RID相关的系统错误：

orientdb = new OrientDB(dbUrl, dbUser,dbPassword, OrientDBConfig.defaultConfig());
session = orientdb.open(databaseName, dbUser, dbPassword);

session.begin();
OVertex v = session.newVertex("Folder");
v.setProperty("name", "RootFolder");
session.save(v);
session.commit();

我正在3个集群中的一台机器上执行一个代码，但是没有其他代码或用户与该集群交互。我还阅读了有关乐观交易的信息，但在这里，100％的时间抛出了异常。我认为例外是在触发 session.commit（）

这是错误：

由于错误的RID在提交时创建记录时发生OConcurrentcreateException
