Cassandra 卡桑德拉收割机：维修一再推迟和卡住

卡桑德拉收割机v2.0.3 卡桑德拉3.11.5.1版

每天我都在一个键空间上运行修复，从几周前开始，修复就一直没有结束。 以下是摘自收割者仪表板的信息表：

我还注意到，收割者日志中同样的信息重复了无数次：

几周前，此修复仅持续几个小时，启动了4个线程。我试图减少修复中使用的螺纹数量，但结果没有改变，修复仍然卡住

我还尝试了滚动重启（我也重启了收割者），但没有成功

你知道这种行为吗？

面对同样的问题。收割者运行了40多天，在试图修复最后一段时花费了30多天。我们使用的是收割者2.0.5版，卡桑德拉3.11.2版也面临同样的问题。收割者运行了40多天，在试图修复最后一段时花费了30多天。我们使用的是收割者2.0.5版和卡桑德拉3.11.2版
