ArangoDB突然启动失败

Question

我已经在ArangoDB上评估了几天。然而，今天我吃完午饭回来后，我发现我的开发机器上的ArangoDB不再工作了。我不知道发生了什么。在此之前，它工作得很好。这发生在我吃完午饭后，试图访问localhost:8529web用户界面，但没有成功，我试图重启windows，操作系统提示我更新并重启。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。供您参考，我使用的是Windows 8.1。我的ArangoDB版本是2.3.4。我还试着使用控制台命令arangod。这就是我现在能看到的。

对我来说，这看起来是一个非常严重的问题。我计划在评估后的将来将ArangoDB投入生产。我只是担心这个问题会发生在我的生产服务器上。任何帮助都将不胜感激。

不幸的是，输出非常具有误导性。测试数据创建和删除了大量的数据库和集合。这两个操作非常昂贵，而且需要很长时间才能恢复。在正常操作中，这不是问题，因为您不会在一次运行中创建100个数据库。但在测试过程中，这种情况可能会发生。效果有两个方面:在恢复过程中打印警告，这并不是真正正确的。集合/数据库确实已删除。我们在ArangoDB 2.4版本中修复了此问题。其次，它需要很长时间才能恢复，因为手术费用很高。
