内存不释放（来自收藏） [英] Memory doesn't release (from collections)

问题描述

您好，我正在使用多个队列集来存储一些数据（大约20,000个/ b $ b条目分为两个集合）。当我在Windows

任务管理器中查看进程时，我可以看到当收集开始时内存增加

fill。但是，当我停止线程并清除队列（并将

实例设置为空）时，内存根本不会丢失。


我在做什么有什么不对吗？


谢谢！

Hello, I am using several queue collections to store some data (about 20,000
entries split across 2 collections). When I view the process in the Windows
task manager I can see the memory increasing when the collections start to
fill. However, when I stop the thread and clear the queues (and set the
instance to nothing) the memory does not drop at all.

Am I doing something wrong?

Thanks!!

推荐答案

仅仅因为一个对象有资格进行垃圾收集，所以没有是的意思是

立即收集垃圾。


当垃圾收集器决定运行时，任何符合条件的东西都会得到

收集。在那之前，它会坐在那里占用记忆。

Just because an object is eligible for garbage collection, doesn''t mean it
gets garbage collected right away.

When the garbage collector decides to run, then anything eligible will get
collected. Until then it will sit there taking up memory.

有没有办法强迫垃圾收集？

仅仅因为一个对象是有资格进行垃圾收集，并不意味着它会立即收集垃圾。

当垃圾收集器决定运行时，那么任何符合条件的垃圾都将被收集。在那之前，它会坐在那里占用记忆。

是的，你可以使用gc.collect但不管我让程序坐了2个小时

它仍然没有释放内存。我甚至设置了一个断点来确保

该课程被设置为空。

Yes, you can use gc.collect but no matter I let the program sit for 2 hours
and it still didn''t free the memory. I even set a breakpoint to make sure
the class was set to nothing.
