Aldrin Piri commented on MINIFI-390:
------------------------------------
I also tested zip compression (.zip) instead of gzip (.gz) and cannot seem to
reproduce or at least it does not develop as quickly.
> Logback archiving can cause issues with rollover when compression is enabled
> ----------------------------------------------------------------------------

> Key: MINIFI-390
> URL: https://issues.apache.org/jira/browse/MINIFI-390
> Project: Apache NiFi MiNiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 0.2.0
> Reporter: Aldrin Piri
>
> At high rates of logging, the compression of archived log files configured in
> logback can cause an unbounded growth of file size despite totalSizeCap.
> The issue can be seen in the following APP appender and triggered with a
> root-level of DEBUG.
> {code}
> <appender name="APP_FILE"
> class="ch.qos.logback.core.rolling.RollingFileAppender">
>
> <file>${org.apache.nifi.minifi.bootstrap.config.log.dir}/minifi-app.log</file>
> <rollingPolicy
> class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
> <!--
> For daily rollover, use 'app_%d.log'.
> For hourly rollover, use 'app_%d{yyyy-MM-dd_HH}.log'.
> To GZIP rolled files, replace '.log' with '.log.gz'.
> To ZIP rolled files, replace '.log' with '.log.zip'.
> -->
>
> <fileNamePattern>${org.apache.nifi.minifi.bootstrap.config.log.dir}/minifi-app_%d{yyyy-MM-dd_HH}.%i.log</fileNamePattern>
> <!-- Keep 10 rolling periods worth of log files-->
> <maxHistory>1</maxHistory>
> <!-- Max size each log file will be-->
> <maxFileSize>10MB</maxFileSize>
> <!-- Provide a cap of 10 MB across all archive files -->
> <totalSizeCap>1000MB</totalSizeCap>
> </rollingPolicy>
> <immediateFlush>true</immediateFlush>
> <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
> <pattern>%date %level [%thread] %logger{40} %msg%n</pattern>
> </encoder>
> </appender>
> {code}
> This seems to be related to https://jira.qos.ch/browse/LOGBACK-1162 which is
> currently in progress. We should monitor this progression and incorporate
> the updated dependency when released. The workaround for those environments
> experiencing this is to disable archiving (by removing the .gz from the
> filename pattern).
