log4j:ERROR Failed to rename

Question

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)

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

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)

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

here my log4j xml

It appears that if you're running windows this is a known bug:
