Tomcat Java GC問題Linux

我在Ubuntu上運行Tomcat Web服務器（7.0）。我在我的本地Windows機器上使用Java 1.6使用相同的War文件，我不會遇到任何問題。然而，在Linux機器上，我的tomcat在一段時間後失敗或停止工作，並且出現Java GC異常。它從這些錯誤：Tomcat Java GC問題Linux

Jul 10, 2011 4:29:05 PM org.apache.catalina.startup.HostConfig checkResources INFO: Undeploying context [/manager] Jul 10, 2011 4:29:05 PM org.apache.catalina.session.StandardManager doUnload SEVERE: IOException while saving persisted sessions: java.io.FileNotFoundException: /home/infocomm/tomcat/work/Catalina/localhost/manager/SESSIONS.ser (No such file or directory) java.io.FileNotFoundException: /home/infocomm/tomcat/work/Catalina/localhost/manager/SESSIONS.ser (No such file or directory)

然後這些錯誤：

然後最後的Tomcat停止這些錯誤響應：

INFO: The destroy() method was called on component [StandardContext[/host-manager]] after destroy() had already been called. The second call will be ignored.

Exception in thread "ContainerBackgroundProcessor[StandardEngine[Catalina]]" java.lang.OutOfMemoryError: PermGen space

希望得到任何幫助。這隻發生在我退出啓動Tomcat應用程序的遠程shell之後。

確實tomcat（當用特定的用戶帳號運行時）有權訪問這個文件，它應該有足夠的權限創建，更新&刪除該文件。

/home/infocomm/tomcat/work/Catalina/localhost/manager/SESSIONS.ser

在Windows

它非常罕見的爲這種情況浮出水面，除非你已經開始Tomcat作爲一個非特權用戶。

是的，它有這個特權。我注意到這隻發生在我試圖運行Tomcat的遠程shell時。我嘗試使用nohup bin/startup.sh> console.log 2> console.err Abhishek

命令運行它你不應該在你的命令中需要'nohup'嗎？ – Mikaveli
