Jason Flores created LOGBACK-1297:
-------------------------------------
Summary: Logback fails to roll once the file count exceeds 1000
Key: LOGBACK-1297
URL: https://jira.qos.ch/browse/LOGBACK-1297
Project: logback
Issue Type: Bug
Affects Versions: 1.2.3
Environment: Windows Server 2012 R2
Processor: Intel Xeon CPU E5-2676 v3 @ 2.40GHz
Memory: 4Gb
Reporter: Jason Flores
Assignee: Logback dev list
Attachments: logqueue-rolling-0.png, logqueue-rolling-1.png
Using the configuration below, copied from Chapter 4: Appenders, of the Logback
Manual I've modified the maxFileSize, maxHistory, and totalSizeCap values.
{{<?xml version="1.0" encoding="UTF-8"?>}}
{{<!-- -Dlogback.configurationFile=/path/to/config.xml -->}}
{{<configuration scan='true' scanPeriod='30 seconds'>}}{{<appender name='FILE'
class='ch.qos.logback.core.rolling.RollingFileAppender'>}}
{{ <file>3mlogqueueforwardservice.log</file>}}
{{ <rollingPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">}}
{{ <!-- rollover daily -->}}
{{
<fileNamePattern>3mlogqueueforwardservice-%d\{yyyy-MM-dd}.%i.log</fileNamePattern>}}
{{ <!-- each file should be at most 5MB, keeping 15 days worth of history, but
at most 200MB -->}}
{{ <maxFileSize>20MB</maxFileSize>}}
{{ <!-- the maximum number of archive files to keep, asynchronously deleting
older files -->}}
{{ <maxHistory>2</maxHistory>}}
{{ <!-- the total size of all archive files -->}}
{{ <totalSizeCap>100MB</totalSizeCap>}}
{{ </rollingPolicy>}}
{{ <encoder>}}
{{ <charset>UTF-8</charset>}}
{{ <pattern>%date %level [%thread] %logger\{10} [%file:%line] %msg%n</pattern>}}
{{ </encoder>}}
{{ </appender>}}{{<logger name="com.mmm.his" level='info' additivity='false'>}}
{{ <appender-ref ref='FILE' />}}
{{ </logger>}}
{{ <root level='warn'>}}
{{ <appender-ref ref='FILE' />}}
{{ </root>}}
{{</configuration>}}
For this configuration I should only ever have 5 files of ~20mb. The rolling
functionality appears to work fine when the index %i is < 1000, after which the
totalSizeCap fails and files are endlessly written at ~20mb until all the
available space on the machine is consumed. The log files contain no
indication of Logback failing...
The two images attached show the log file rolling successfully and then failing
to remove files as the index increases > 1000. I've replicated this several
times, but only by watching the logs grow and inspecting the contents of the
log; our application collects and logs rather quickly.
Is there an interim solution? We're stucking restarting and deleting each time
the problem occurs.
