[logback-user] RollingFileAppender does not roll after max size exceeds

[amit shah]

Hello,

I am using using logback version 1.0.9 with slf4j 1.7.2. I see my log file
not getting rolled over even after the maxFileSize exceeds. I see that the
new logs are still logged to the same file and its size continuously
increasing. My configuration is as below

  <appender name="WEB_LOG"
class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>web.log</file>
        <rollingPolicy
class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <fileNamePattern>web%i.log</fileNamePattern>
            <minIndex>1</minIndex>
            <maxIndex>9</maxIndex>
        </rollingPolicy>
        <triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <maxFileSize>20MB</maxFileSize>
        </triggeringPolicy>
        <encoder>
            <pattern>%date [%thread] %-5level %logger{36} %line -
%msg%n</pattern>
        </encoder>
    </appender>

The current log file size is over 55 mb. I would like to know if there is
any information that I could capture while this issue is seen in the
production environment since I assume this would be a rare bug being seen.

Regards,
Amit.
