Glassfish 4.1 java。lang.OutOfMemoryError异常

Question

我的应用程序已经在glassfish服务器上运行了很长一段时间，今天一位应用程序用户警告我服务器意外关闭。在服务器日志中，我看到以下堆栈跟踪（服务器关闭前10个相同的堆栈跟踪）：

我试图找出这个异常的原因，但我找不到任何有用的解释-没有一个答案描述这种异常（GRIZZLY0013：使用java.lang.OutOfMemoryError执行FilterChain期间的异常）。请任何人向我解释为什么会发生这种情况，我能做些什么来防止它再次发生

多谢各位

Answer 1

java.lang.OutOfMemoryError通常指向内存泄漏。这可能是由您的应用程序以及Glassfish造成的，因为两者都运行在同一个JVM中。异常仅表明JVM不能分配新对象，但不能告诉内存中的内容

从stacktrace中，我猜Glassfish在将响应发送到浏览器之前正在尝试处理响应。在通过HTTP协议发送之前，resposne可能太大，无法在内存中压缩。尝试查看其他日志，以重建请求正在执行的操作以及它是否能够生成巨大的响应。但这只是一个猜测，因为可能还有其他与正在处理的请求完全无关的内存消耗原因

您还可以通过设置JVM选项-Xmx来增加Glassfish的内存限制

Answer 2

服务器内存不足，然后JVM可能崩溃。写入HTTP响应时出错

设置JVM选项-XX:+heapdumponotofmemoryError，这样如果再次发生这种情况，您可以得到一个HeapDump，您可以使用Eclipse内存分析器工具包之类的工具进行分析，这样您就可以找出所有堆的用途
