[ http://jira.qos.ch/browse/LBCORE-153?page=com.atlassian.jira.plugin.system.i... ] Ceki Gulcu commented on LBCORE-153: ----------------------------------- No, this is not a known issue. Are the log entries being written to the newly created file and the rotated file identical? Put differently, is it possible that different processes are writing to those files? Are you using SiftingAppender?

Replicated log entries with RollingFileAppender -----------------------------------------------

Key: LBCORE-153 URL: http://jira.qos.ch/browse/LBCORE-153 Project: logback-core Issue Type: Bug Components: Rolling Affects Versions: 0.9.18 Environment: JDK 6, Windows 2008 Server Reporter: Silvano Maffeis Assignee: Logback dev list Priority: Critical

Hi We use logback 0.9.18 and SLF4J 1.5.10. After monthly log rotation we noticed that new log entries were being appended both to the newly created file and also to the rotated file of the previous month. Is this a known issue? Below is the config snippet. Regards, Silvano <appender name="XML" class="ch.qos.logback.core.rolling.RollingFileAppender"> <File>${viperats.logdir}txplugin.xml.log</File> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%d{yyyy-MM-dd HH:mm:ss}%n%msg------------------------------------------------%n</pattern> </layout> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>${viperats.logdir}/txplugin.xml.log-%d{yyyy-MM}</FileNamePattern> </rollingPolicy> <Append>true</Append> </appender>
