Description

Dears,

I have very simple configuration of the RollingFile appender

<RollingFile name="RollingFile" fileName="${env:LOG_DIR}/${application}/endpoint.log"
    filePattern="$${env:LOG_DIR}/$${application}/$${date:yyyy-MM}/endpoint-%d{yyyy-MM-dd}-%i.log">
    <PatternLayout>
        <Pattern>%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n</Pattern>
    </PatternLayout>
    <Policies>
        <TimeBasedTriggeringPolicy />
    </Policies>
    <DefaultRolloverStrategy max="5"/>
</RollingFile>

This configuration works partly good. Every day there is created file in folder YYYY-MM.
That is expected.
What is not expected - it is that the process is not limited at all. I mean there are more than 5 files in all folders.

Questions:
Is it something wrong with configuration?
is max=5 considered to be the numeber of files or folders (in my case months)?
or max=5 is ignored at all.

I had read some hints in SO: How does Log4j2 DefaultRolloverStrategy's max attribute really work?

Thanks in advance for help.
