I am using version 1.1.7 with configuration like this:

<appender name="DAILY" class="ch.qos.logback.core.rolling.RollingFileAppender">
  <file>${LOG_FILE_PATH}/${LOG_FILE_NAME}</file>
  <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <fileNamePattern>${LOG_FILE_PATH}/history/${LOG_FILE_NAME}.%d{${LOG_ROLLER_PATTERN}}.gz</fileNamePattern>
    <maxHistory>10</maxHistory>
  </rollingPolicy>
<encoder>
  <charset>UTF-8</charset>
  <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS}%-5level [%thread] [us.%X{user}.%X{method}] %logger{36}
:%line - %msg%n</pattern>
  </encoder>
</appender>

I get a lot of tmp files, also one of the dates did not roll, I'm guessing because of this. Here is the history folder (which is missing core.log.2016-11-15.gz):
rw-rr- 1 was2 was2 614 Nov 9 00:00 core.log.2016-11-08.gz

And here is the main folder full of .tmp files, which also contains one log from Nov 15-th im guessing this did not roll:

This is out test server. Our production is even worse. There is hourly rolling.
