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
