我使用ChronicleQueue.close()和强制运行GarbageCollector来确保旧的cq文件被我的进程释放:

var oldQueue = queue;
  this.queue = SingleChronicleQueueBuilder.binary(logDir)
            .rollCycle(RollCycles.DAILY)
            .build();
  // make sure all appenders are update
  logHandlerSet.forEach(logHandler -> logHandler.updateAppender(queue));
  oldQueue.close();
   ... after some delay ...
    LOGGER.debug("Running gc");
    System.gc();
    LOGGER.debug("gc done");

我也对finalizer做了同样的操作。然而,当finalizer运行时,我得到了这个异常:

这种情况发生了几百次,我在Chronicle Queue 5.23.37和5.25ea3中遇到过。我做错了什么吗?有没有更好的方法来释放CQ文件?

我发现了我的问题:我创建了一个没有关闭的ExcerptTailer。将其 Package 在try-with-resources中解决了这个问题。
