我正在运行一个产品。
我正在使用这些版本：
服务器规格为总内存128GB。我用的是24GB。和 WindowServer 2019 标准。
此外，“nodetool flash”每四个小时运行一次。
如果您查看下面的 Cassandra 日志，您可以看到工作一直持续到时间 14:47:05.865。

中间Cassandra日志中没有留下任何错误日志。
请帮我解决我缺少的部分。
根据您发布的日志条目，文件系统级别似乎存在问题，其中一个临时文件被进程锁定，因此其他文件无法访问。
Cassandra 使用的 Java 文件 I/O 库在 Windows 上一直存在问题，尤其是 NTFS。对于用户来说，这一直是问题的根源，我们认为继续支持该项目并不好（请参阅本线程中的讨论）。
我们最终在 Cassandra 4.0 中完全放弃了 Windows 支持 (CASSANDRA-16171)。
为 Windows 用户推荐的解决方法是：
