I get this error "log4j: ERROR Failed to rename" in my tomcat server log. I have several DailyRollingFileAppender in my xml log4j file. And each appender points to a different file. Only one instance of the application is running. I used the Handle utility and ran the command (with the log file name as parameter)
handle -f ams-app.log and result Tomcat7.exe pid: 5032 Type: File 54C: E: \ apps \ ams \ logs \ ams-app.log
From this, I assume that there is only one lock in the file. My environment is Windows Server 2008, tomcat 7.0 and Java 6 and slf4j-log4j12 (1.5.6)
This problem did not occur when the same application was hosted on an AIX server. I googled this problem and it seems a specfic window. Also I don't want to use DatedFileAppenders or any forked log4j. Does it rarely solve problems. Any suggestions for resolving this issue are welcome. Thanks
here is my log4j xml
