Java 有人能发现内存泄漏吗？

java memory memory-leaks

Java 有人能发现内存泄漏吗？,java,memory,memory-leaks,Java,Memory,Memory Leaks,你好，我一直在努力寻找这个内存泄漏了一段时间，现在没有运气 我所拥有的是一个服务器，它为flash客户端安全接受请求提供服务。它只发送一个数据包，但有能力容纳超过10000个并发连接？如果它也有可能是65534 无论如何，在24小时内为大约210000多名用户提供服务后，内存使用量从12000MB增加到74000MB。我想它会稳定下来，并一直在想，也许是一些东西已经被拆开包装注册，并将被重新使用。但在48小时后，它的容量将达到90MB，按照这个速度，我必须每2天重新启动服务器，以防止OutOfM

你好，我一直在努力寻找这个内存泄漏了一段时间，现在没有运气

我所拥有的是一个服务器，它为flash客户端安全接受请求提供服务。它只发送一个数据包，但有能力容纳超过10000个并发连接？如果它也有可能是65534

无论如何，在24小时内为大约210000多名用户提供服务后，内存使用量从12000MB增加到74000MB。我想它会稳定下来，并一直在想，也许是一些东西已经被拆开包装注册，并将被重新使用。但在48小时后，它的容量将达到90MB，按照这个速度，我必须每2天重新启动服务器，以防止OutOfMemoryException（我还没有得到它，但我知道只有300MB的ram可用）

不管怎样，如果有人有时间愿意帮助我，我会非常感激，这是消息来源

可能不是唯一的问题，但我认为您从未调用
pendingChanges.remove（）

此外，您应该尝试使用探查器-它可能比手动查看更容易。

可能不是唯一的问题，但我认为您从未调用

此外，您应该尝试使用档案器-这比手动查看容易。

您的课堂上有几个集合：

private List<ChangeRequest> pendingChanges = ...;
private Map<SocketChannel, List<ByteBuffer>> pendingData = ...;

private List pendingChanges=。。。；
私有映射挂起数据=。。。；
这些将是我的第一个检查目标——这些目标是否会随着时间的推移而无限增长？是否正确删除未使用的元素？在正确的位置进行一些调试打印输出应该能够为您提供答案

如果这并没有给你一个明显的解决方案，我支持关于尝试内存分析器的意见。

你是否让任何连接隐式打开

如果远程计算机打开了一个连接，并且该变量不在作用域内，那么它仍然处于活动状态，并且在连接断开（由另一方或网络故障）之前不会被垃圾收集。

是否隐式打开任何连接

如果远程机器打开了一个连接，并且变量不在范围内，那么它仍然处于活动状态，并且在连接断开（由另一方或网络故障）之前不会被垃圾收集。

在运行了一个快速的黑客数据包垃圾邮件发送者应用程序之后

import java.io.*;

public class Spam {

public static int sbyte;
