------------------------------------------
Summary: SizeBasedTriggeringPolicy and FixedWindowRollingPolicy :
file grows enormously in some cases
Key: LOGBACK-1431
URL: https://jira.qos.ch/browse/LOGBACK-1431
Project: logback
Issue Type: Bug
Components: logback-classic, logback-core
Affects Versions: 1.2.3
Environment:
Logback 1.2.3,
RHEL 6
Reporter: Alisa Martirosyan
Assignee: Logback dev list
Hi there,
Using logback 1.2.3.
We have SizeBased and FixedWindow policy described as follows:
<appender name="METRICS"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>\{filename}</file>
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>\{filename}.%i.log</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>9</maxIndex>
</rollingPolicy>
<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>20MB</maxFileSize>
</triggeringPolicy>
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<layout class="com.avaya.ept.common.logging.layout.CLFLayout">
<pattern>|%thread|%level|%logger\{15}|%msg%n</pattern>
</layout>
</encoder>
</appender>
Recently we've faced the issue when log file \{filename}-1.log grows to the
enormous size of 40gb without any particular reason. After removing this log
and restarting the application log continues to rotate normally, on ~20mb size
mark.
We could not analyze the logs as they causes the system to freeze (due to lack
of free disk space) and had to be removed ASAP. Is there any particular reason
why this could be happen?
Using RHEL 6.
