我们在tomcat 5.5上使用JDK6生产环境。上周将系统升级到tomcat 7 JDK 7.从那以后，我们每天都会收到OutOfMemoryError。
我添加了标记来捕获OOM上的堆转储。使用Memory Analyzer Tool分析它们。转储显示可疑对象com.sun.org.apache.xml.internal.resolver.Catalog浅大小〜56B，保留大小~1.3 GB，带有以下堆栈跟踪

我怀疑发生此问题是因为我正在调用另一个Web服务。
我使用以下JVM选项，最小内存设置为500米，最大值为1500米
-XX:MaxPermSize=170m
-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled
-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=C:\heaplogs\

这听起来与this bug非常相似。如果它是相同的，则CatalogManager将保留对所创建的CatalogEntry的每个实例的引用。该链接建议您可以重用相同的服务对象，但每次调用时都必须重新初始化它，以强制CatalogManger放弃其存储的引用。
该帖子中的另一篇文章建议尝试使用以下内容强制CatalogManger放弃引用
-Dxml.catalog.staticCatalog=false
如果上述方法不起作用，我个人非常幸运Axis2消费SOAP。

我能想到的唯一一个显而易见的事情 - 你有内存泄漏。
您可以使用jvisualvm来检测在调用之后保存对com.sun.org.apache.xml.internal.resolver.Catalog个对象的引用的GC根。
这是一个非常好的免费工具。
您可以通过Google搜索来找到有关如何使用jvisualvm的指南。

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“
=＆GT;重启你的tomcat

你绝对应该让MAT告诉你谁持有这些参考资料，为什么他们还活着而不是GCed。
另一种选择是尝试使用专门的内存泄漏检测工具，例如Plumbr。

每当你得到一个OOM，它应用了一些导致内存泄漏的功能。发现内存泄漏可能很困难，但因为你已经缩小了嫌疑人的范围。只需检查webservice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是你的webservice客户端中的一些代码正在创建数组或复制它。
另外，请检查您的Vm args是否设置正确。
