TitanFactory.open（config）：没有锁可用

Question

我在尝试打开下面的TitanGraph实例时遇到了无锁定异常（由sleepycat引起）。可能导致它的任何导致？我错过了什么吗？我已经检查了该目录的许可和所有权，但没有运气。

TitanGraph titanGraph;
Configuration config = new BaseConfiguration();
Configuration storage = config.subset("storage");
storage.setProperty("backend", "local");
storage.setProperty("directory", "data/titan");
titanGraph = TitanFactory.open(config);

引起：
