我在ArangoDB上进行了几天的评估。然而，今天我从午餐后退了下来，我发现我的机器中的ArangoDB不再工作了。我没有找到正在发生的事情的线索。在此之前它工作正常。它发生在我从午餐回来并尝试访问localhost：8529 web ui但没有成功的时候我试图重新启动Windows，操作系统提示我更新并重新启动。重新启动后，我也无法启动Arango Web界面。
我尝试重新启动Arango服务，但似乎没有成功。为了您的信息，我使用的是Windows 8.1。我的ArangoDB版本是2.3.4。我也尝试使用控制台命令arangod。这就是我现在能看到的。

对我来说，这看起来非常严重。我计划在评估后将ArangoDB投入生产。我只是担心这个问题会在我的生产服务器中发生。任何帮助将非常感谢。
答案 0 :(得分：1)
遗憾的是，输出非常具有误导性。测试数据创建并删除了大量数据库和集合。这两项操作非常昂贵，需要花费大量时间才能恢复。在正常操作中，这不是问题，因为您不会在运行中创建100个数据库。但在测试期间，这可能发生。效果有两个：在恢复期间打印警告，这不是真正正确的。确实删除了集合/数据库。我们在ArangoDB 2.4版本中修复了这个问题。其次，恢复需要很长时间，因为操作很昂贵。
