我们在 JDK6 的 Tomcat 5.5 上拥有生产环境。上周将系统升级到 tomcat 7 JDK 7。从那时起，我们每天都会收到 OutOfMemoryError。

我添加了标志来捕获 OOM 上的堆转储。使用内存分析器工具分析它们。转储显示可疑对象com.sun.org.apache.xml.internal.resolver.Catalog~56B 的浅大小和 ~1.3 GB 的保留大小，具有以下堆栈跟踪

我怀疑发生此问题是因为我正在调用另一个 Web 服务。

我正在使用以下 JVM 选项，最小内存设置为 500m，最大内存设置为 1500m

-XX:MaxPermSize=170m
-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled
-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=C:\heaplogs\

这听起来与这个错误非常相似。如果相同，CatalogManager 将保存对曾经创建的每个 CatalogEntry 实例的引用。该链接建议您可以重用相同的服务对象，但您必须在每次调用时重新初始化它以强制 CatalogManger 放弃其存储的引用。

线程中的另一篇文章建议尝试以下方法以强制 CatalogManger 放弃引用

-Dxml.catalog.staticCatalog=false

就我个人而言，如果上述方法不起作用，我对Axis2使用 SOAP非常幸运。

您绝对应该要求 MAT 向您展示谁持有这些引用，为什么它们仍然存在而不是 GC。

另一种选择是尝试专门的内存泄漏检测工具，例如Plumbr。

我可以假设的唯一一件明显的事情 - 你有内存泄漏。

您可以在 ws 调用后使用jvisualvm来检测 GC 根，这些根包含对对象的引用。com.sun.org.apache.xml.internal.resolver.Catalog这是一个非常好的免费工具。

您可以通过谷歌搜索找到有关如何使用的指南jvisualvm。

从 tomcat/bin 打开 catalina.sh。

然后

JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m -XX:MaxPermSize=256m - XX:+DisableExplicitGC"

=> 重启你的tomcat

每当您收到 OOM 时，就会发现某些功能会导致内存泄漏。查找内存泄漏可能很困难，但因为您已经缩小了嫌疑人的范围。只需检查 Web 服务客户端中是否有任何可能导致此问题的代码。

从堆栈跟踪中，我怀疑您的 Web 服务客户端中的一些代码正在创建数组或复制它。

另请检查您的虚拟机参数是否设置正确。
