是否有人发现他们的ActiveMQ KahaDB或LevelDB商店的磁盘空间正在增长？
我们正在使用以下内容：
KahaDB
当将ActiveMQ与KahaDB一起使用时，我已经看过db * .log文件最初从db-1.log到“db-2.log”再到“db-3.log”之类的“leap-frog”，依此类推正在按预期清除（删除）旧的db * .log文件。然后在某个时刻可能是10个小时之后，旧的db * .log文件停止清理;出现新的db * .log文件，KahaDB开始以每天大约4 GB的速度扩展。当它最终达到我们配置的50 GB上限时，服务器当然会停止工作。
似乎少数消息未能过期（尽管给出了TTL）并因此阻止正常清理。我试图手动删除旧的db * .log文件，但是我被阻止这样做，并警告说这些文件仍在使用中。
KahaDB db * .log文件在文本编辑器中是“半可读”（！）;即我可以识别应用程序消息，但这并没有告诉我很多真正发生的事情。
性LevelDB
我最近尝试将LevelDB与ActiveMQ 5.13.2一起使用，并且该商店似乎仍然会扩展得更慢（每天大约200 MB）。
我相信LevelDB数据存储使用压缩;大多数文件看起来都是二进制的，因此没有合适的阅读器/浏览器就会非常不透明。
是否有人发现或实现了读取/浏览KahaDB或LevelDB消息存储库的非持久性消息的工具？
