> Log files do not seem to be rolling up to the max number of files as specified in DefaultRolloverStrategy while utilizing a SizeBasedTriggeringPolicy. It is just rolling just to 1 file.
> Simple repro:
> log4j2.xml
> {code}
> <?xml version="1.0" encoding="UTF-8"?>
> <Configuration status="INFO" name="MyApp">
> <Appenders>
> <RollingFile name="rolling"
> fileName="__logs__/rolling.log"
> filePattern="__logs__/rolling.log.%i"
> immediateFlush="true">
> <PatternLayout pattern="%d %5p [%t] (%c) - %m%n"/>
> <SizeBasedTriggeringPolicy size="1MB"/>
> <DefaultRolloverStrategy max="10"/>
> </RollingFile>
> </Appenders>
> <Loggers>
> <Root level="INFO">
> <AppenderRef ref="rolling"/>
> </Root>
> </Loggers>
> </Configuration>
> {code}
> MyApp.scala:
> {code}
> import scala.util.Random
> import org.apache.logging.log4j.LogManager
> object MyApp extends App {
> val log = LogManager.getLogger(this.getClass)
> var counter = 0L
> var bytes = new Array[Byte](1000)
> while (true) {
> Random.nextBytes(bytes)
> log.info(f"Log statement: $counter%08x ${bytes.mkString}")
> counter += 1
> Thread.sleep(5)
> }
> }
> {code}
> If you run that against 2.7, things roll fine. If you run that against 2.8, you'll only see rolling.log & rolling.log.1 in the __logs__ folder.
