内存不足错误 Java堆内存空间

Question

内存不足错误 Java堆内存空间

4

我们的生产环境使用的是Tomcat 5.5和JDK6。上周我们将系统升级到了Tomcat 7和JDK7。自那时起，我们每天都会出现OutOfMemoryError错误。

我添加了一些标志来捕获OOM时的堆转储信息，并使用内存分析器工具进行了分析。倒掉中显示了一个可疑对象com.sun.org.apache.xml.internal.resolver.Catalog，其浅大小约为56B，保留大小约为1.3 GB，并伴随以下堆栈跟踪。

我猜测这个问题是由于我调用了另一个Web服务引起的。

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\

为什么不直接升级到新版的Tomcat呢？ - Pavel Horal

你允许了多少堆空间？我怀疑Java 7可能需要更多一点（可能是几百兆字节），但如果超过这个数，我会感到惊讶。顺便说一下，我建议确保你安装了Java 7更新版本25至40。 - Peter Lawrey

堆空间为1500 MB。Tomcat 7.27已经存在。我必须有一些理由在生产环境中升级它。 - orak

我误读了问题（以为你仍在使用Tomcat 5.5）。然后我会尝试升级/降级JAX-WS依赖项并查看发生了什么（https://www.java.net//forum/topic/glassfish/metro-and-jaxb/memory-leaks-consuming-web-services）。 - Pavel Horal

我唯一能想到的明显问题就是你有一个内存泄漏。

你可以使用 jvisualvm 来检测在 Web Service 调用后仍然持有对 com.sun.org.apache.xml.internal.resolver.Catalog 对象引用的 GC 根。这是一个非常好的免费工具。

你可以通过谷歌搜索找到关于如何使用 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"

=> 重新启动您的tomcat

你绝对应该要求MAT显示给你谁在持有这些引用，为什么它们仍然存活而不被垃圾回收。

另一个选择是尝试专门的内存泄漏检测工具，比如 Plumbr。

无论何时您遇到OOM，都意味着某些功能会导致内存泄漏。查找内存泄漏可能很困难，但由于您已经缩小了嫌疑对象，请检查一下WebService客户端中是否有任何可能引起此问题的代码。

从堆栈跟踪中，我怀疑您的WebService客户端中存在一些创建数组或复制数组的代码。

另外，请检查您的Vm参数是否设置正确。

这听起来非常类似于这个bug。如果是同样的问题，CatalogManager将持有对每个创建的CatalogEntry实例的引用。该链接建议您可以重复使用相同的服务对象，但每次调用都必须重新初始化它，以强制CatalogManger放弃其存储的引用。

该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

如果上述方法行不通，个人建议使用Axis2来消费SOAP服务。
