应用错误收集

背景：我们的YouTrack数据库已损坏。相关的错误报告在此处：https://youtrack.jetbrains.com/issue/JT-48235#comment=27-2952375现在，我正在尝试修复YouTrack内部使用的Xodus数据库的损坏状态。

问题：数据库包含具有已删除实体链接的实体。我的问题是：如何删除或修复这些断开的链接？

关闭YouTrack后，我使用Xodus Entity Browser检查数据库。

我想出了两种可能的解决方案：

重新创建已删除的实体。在我的情况下是Sprint[86-191]。这是行不通的，因为创建新实体不允许我再次选择编号191。相反，它创建了Sprint[86-208]。
删除断开的链接。无法工作，因为为了删除链接，Xodus期望数据库的一致性导致以下堆栈跟踪：

有没有办法解决这种损坏的状态？

如何修复JetBrains Xodus数据库损坏的完整性？
