WAS 6.1和EJB 2.1出现内存不足异常

Question

我的应用程序内存不足，并在一段时间内收到内部服务器错误，之后它会自动恢复，应用程序运行正常。

我的应用程序托管在WAS 6.1上，使用Struts1.1和EJB2.1。以下是错误的应用程序服务器日志。你能在这个问题上帮我一下吗？

Answer 1

java.lang.OutOfMemoryError建议您在应用程序服务器中耗尽内存。为了快速解决这个问题，您可以增加应用程序服务器中的最大堆大小，但通常您应该启用详细gc并生成堆转储。然后分析转储，查找内存泄漏，并了解堆中占用空间的是什么。

您可以使用IBM Support Assistant提供的工具(免费提供)：
