> Hi,
> We have moved from Log4j1.x to Log4j2.17.1 to fix the Log4j vulnerability and
> it is a Java application. This is an EJB project and I have placed the xml
> under src directory. This project is an EAR application. Everything works
> fine but in one application we have below issue. The requirement is Logs
> after reaching max size 15 mb should roll over and create new log file and 30
> such Log files should be generated before it archives the logs to a folder.
> But after moving to Log4j 2.17.1 this is not happening. After reaching the
> max size this log file is getting overridden and data is lost. Also it is
> writing to the folder immediately without creating the 30 max files.
> Below is my Log4j2.xml file.
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="INFO" name="Test" >
> <Properties>
> <Property name="filename">${sys:LOGGING_DIR}/TestLog.log</Property>
> <property name="name">Test</property>
> <property name="pattern">%d [%p] - %c\{1} (%M:%L) - %m%n</property>
> </Properties>
> <Appenders>
>
> <RollingFile name="RollingFile" fileName="${filename}"
>
> filePattern="${sys:LOGGING_DIR}/$${date:yyyy-MM}/${name}-%d\{yyyy-MM-dd}-%i.log.gz">
> <PatternLayout>
> <pattern>${pattern}</pattern>
> </PatternLayout>
> <Policies>
> <TimeBasedTriggeringPolicy /><!-- Rotated everyday -->

> </RollingFile>
> </Appenders>
> <Loggers>
> <Root level="debug">
> <AppenderRef ref="RollingFile" />
> </Root>
> </Loggers>
> </Configuration>
> I tried all the options shown below to use SizeBased, TimeBased and
> DefaultRolloverStrategy but still the file gets overridden
> <Policies>
> <SizeBasedTriggeringPolicy size="10 KB" />
> TimeBasedTriggeringPolicy interval="1" />
> </Policies>
> <DefaultRolloverStrategy max="30"/>
> In the attachment provided after reaching 10Kb it is writing a file
> catcher-2022-04-29-1.log. But again when it reaches 10Kb the logs in this
> file are getting overridden without creating a new file.
> Please let me know what is the issue with my xml file and how to fix this to
> always create a new file after reaching max size of 15 MB and to create 30
> such files before archiving it to a folder.
> Please let me know if you need any more details
> Thanks
