Hi again, is there any chance of making the TimebasedRollingPolicy ever run properly? I've run the tests once more. The current flaw of execution is following: Stage 1: RollingPolicyBase.setParent(FileAppender appender) is called at this stage appender.rawFileProperty() is still Null in spite of configuration file entry Stage 2: TimeBasedRollingPolicy.start() is called at this stage lastCheck time is set and because File property of FileAppender is still Null, last modification time of the log is not read Stage 3: FileAppender.setFile is finally called to set the file name of the log. At this stage it is too late because current system time was assigned to lastCheck at Stage 2 That is the reason, why all applications that do not run as long as TimebasedRollingPolicy trigger event needs, will never ever roll the log file over. Please make it work right if possible. I would do it myself if i could, but i'm pretty new in java and the logback code is too complex for me to make myself comfortable with it. -- View this message in context: http://www.nabble.com/TimeBasedRollingPolicy-tp19756004p23123245.html Sent from the Logback User mailing list archive at Nabble.com.
