我的应用程序的设计方式使得无论何时有人尝试启动它，该应用程序都会关闭自身的其他实例。 （请注意，此操作按预期工作，不应更改）。
我正在使用Akka，我的Actor之一是使用PersistentActor的{{1}}。
应用程序启动时会锁定leveldb，再次启动时<path-to-lock>/LOCK无法锁定文件，因此leveldb无法启动。
经过一番检查，我发现PersistentActor leveldb类是Actor，并且它在LeveldbJournal下以路径system guardian开始。
我希望akka://actor-system/system/akka.persistence.journal.leveldb自行重启，直到可以锁定文件或达到最大重试次数为止。
