log4j:ERROR重命名失败 [英] log4j:ERROR Failed to rename

问题描述

我的tomcat服务器日志中出现此错误"log4j:ERROR重命名失败". 我的log4j XML中有多个DailyRollingFileAppender.每个附加程序都指向不同的文件.该应用程序实例仅运行一次. 我使用了Handle实用程序并运行了命令(以日志文件名作为参数)

I get this error "log4j:ERROR Failed to rename" in my tomcat server log. I have multiple DailyRollingFileAppender in my log4j XML. And each appender points to different file. Only once instance of the application is running. I used Handle utility and run the command (with log file name as parameter)

句柄-f ams-app.log 结果是 Tomcat7.exe pid:5032类型:文件54C:E:\ apps \ ams \ logs \ ams-app.log

handle -f ams-app.log and the result is Tomcat7.exe pid: 5032 type: File 54C: E:\apps\ams\logs\ams-app.log

据此，我假设文件上只有一个锁. 我的环境是Windows Server 2008，tomcat 7.0和Java 6和slf4j-log4j12(1.5.6)

From this I assume there is only one lock on the file. My environment Windows Server 2008, tomcat 7.0 and Java 6 and slf4j-log4j12(1.5.6)

当在AIX服务器上托管相同的应用程序时，不会发生此问题. 我用谷歌搜索了这个问题，它似乎是Windows特有的. 另外，我也不希望使用DatedFileAppenders或任何派生的log4j. 登录是否解决了此类问题. 任何有关如何解决此问题的建议，不胜感激. 谢谢

This problem was not happening when same application hosted on AIX server. I googled this problem and it seems to be windows specfic. Also I am not keen to use DatedFileAppenders or any forked log4j. Does logback solve such issues. Any suggestions on how to solve this problem is appreciated. Thanks

这是我的log4j xml
