There is a memory leak issue in current silverlight project. It occurs in the search function: the memory usage of corresponding IE process increase about 30MB per search, and never get down. Here is the way I found the bug and fix it: 1. download Wi…

首先介绍一下内存泄漏(Memory Leak)的概念,内存泄露是指程序中已动态分配的堆内存由于某种原因未释放或者无法释放,造成系统内存的浪费,导致程序运行速度减慢甚至系统崩溃等严重后果. 最近在使用WPF WebBrowser时,就遇到了Memory Leak的问题. 在主窗体上通过一个按钮点击事件加载包含有WebBrowser控件的窗体,使用这个WebBrowser来浏览网页,然后调用WebBrowser的Dispose()方法,然后调用GC.Collect(),最后关闭当前包含有WebBro…

起因是我们的集群应用(3台机器)新版本测试过程中,一般的JVM内存占用 都在1G左右, 但在运行了一段时间后,慢慢升到了4G, 这是一个明显不正常的现象. 定位 过程: 1.先在该机器上按照步骤尝试重现现场,当发生问题后打开一台机器上JDK的jvisualvm观察JVM内存占用情况,这时明显看到GC很密集,锯齿线很密,几乎压在一起.之后随着时间增加, Heap曲线缓步上升. 这时怀疑是哪里的代码出现了死循环, 产生了大量的垃圾对象频繁被GC. JVM启动的主要参数为-Xms1024M -Xmx1…
