OutOfMemoryError Java堆空間

Question

我們在tomcat 5.5上使用JDK6生產環境。 上周將系統升級到tomcat 7 JDK 7.從那時起，我們每天都會收到OutOfMemoryError。

我添加了標志來捕獲OOM上的堆轉儲。 使用Memory Analyzer Tool分析它們。 轉儲顯示可疑對象com.sun.org.apache.xml.internal.resolver.Catalog淺大小~56B，保留大小~1.3 GB，帶有以下堆棧跟蹤

我懷疑發生此問題是因為我正在調用另一個Web服務。

我使用以下JVM選項，最小內存設置為500米，最大為1500米

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

Answer 1

這聽起來非常類似於這個bug 。 如果它是相同的，則CatalogManager將保留對所創建的CatalogEntry的每個實例的引用。 該鏈接建議您可以重用相同的服務對象，但每次調用時都必須重新初始化它，以強制CatalogManger放棄其存儲的引用。

該帖子中的另一篇文章建議嘗試以下方法強制CatalogManger放棄引用

-Dxml.catalog.staticCatalog=false

就個人而言，如果以上方法不起作用，我已經非常幸運地使用了Axis2來消費SOAP。

Answer 2

我能想到的唯一一個顯而易見的事情 - 你有內存泄漏。

您可以使用jvisualvm來檢測在ws調用后持有對com.sun.org.apache.xml.internal.resolver.Catalog對象的引用的GC根。 這是一個非常好的免費工具。

你可以通過谷歌搜索來找到關於如何使用jvisualvm的指南。

Answer 3

從tomcat / bin打開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”

=>重啟你的tomcat

Answer 4

你絕對應該要求MAT告訴你誰持有這些參考資料，為什么他們還活着而不是GCed。

另一個選擇是嘗試專門的內存泄漏檢測工具，如Plumbr 。

Answer 5

每當你得到一個OOM時，它應用了一些導致內存泄漏的功能。 發現內存泄漏可能很困難，但因為你已經縮小了嫌疑人的范圍。 只需檢查webservice客戶端中是否有可能導致此問題的代碼。

從堆棧跟蹤中我懷疑是你的webservice客戶端中的一些代碼正在創建數組或復制它。

另外，請檢查您的Vm args是否正確設置。
