log4j:ERROR Failed to rename

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 ``` <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <appender name="CONSOLE_APPENDER" class="org.apache.log4j.ConsoleAppender"> <errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/> <param name="Target" value="System.out"/> <param name="Threshold" value="DEBUG"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%n %d{yyyy/MM/dd HH:mm:ss} %-5p %x %M(%F:%L) - %m %n"/> </layout> </appender> <appender name="APP_APPENDER" class="org.apache.log4j.DailyRollingFileAppender"> <errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/> <param name="datePattern" value="yyyy-MM-dd"/> <param name="file" value="E:/apps/ams/logs/ams-app.log"/> <param name="append" value="true"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%n %d{yyyy/MM/dd HH:mm:ss} %-5p %x %M(%F:%L) - %m %n"/> </layout> </appender> <appender name="SQL_APPENDER" class="org.apache.log4j.DailyRollingFileAppender"> <errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/> <param name="datePattern" value="yyyy-MM-dd"/> <param name="file" value="E:/apps/ams/logs/ams-sql.log"/> <param name="append" value="true"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%n %d{yyyy/MM/dd HH:mm:ss} %-5p %x %M(%F:%L) - %m %n"/> </layout> </appender> <appender name="Quartz_APPENDER" class="org.apache.log4j.DailyRollingFileAppender"> <errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/> <param name="datePattern" value="yyyy-MM-dd"/> <param name="file" value="E:/apps/ams/logs/ams-Quartz.log"/> <param name="append" value="true"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%n %d{yyyy/MM/dd HH:mm:ss} %-5p %x %M(%F:%L) - %m %n"/> </layout> </appender> <logger name="org.springframework"><level value="WARN"/></logger> <logger name="flex.messaging.log.ServletLogTarget"><level value="WARN" /></logger> <logger name="net.sf.jasperreports"><level value="WARN" /></logger> <logger name="net.sf.jasperreports.engine.fill"><level value="WARN" /></logger> <logger name="org.apache.commons.beanutils"><level value="WARN" /></logger> <logger name="jdbc.sqltiming" additivity="false"><level value="DEBUG"/><appender-ref ref="SQL_APPENDER"/></logger> <logger name="org.quartz" additivity="false"><level value="WARN" /><appender-ref ref="Quartz_APPENDER"/></logger> <logger name="org.quartz.SchedulerException"><level value="ERROR" /><appender-ref ref="MAIL_APPENDER"/></logger> <logger name="org.hmil.ams.BatchDAO" additivity="false"><level value="INFO"/><appender-ref ref="Quartz_APPENDER"/></logger> <root> <priority value="debug"></priority> <appender-ref ref="APP_APPENDER" /> <appender-ref ref="CONSOLE_APPENDER"/> </root> ```
