[logback-user] Logback suddenly stopped logging

[Jorge Morales Pou]

>which version are you using?

We are using SLF4J 1.5.10 and Logback 0.9.18.
We have reverted to log4j as it is working fine with log4j.

>> We have logback configured with this configuration:
>>
>>    <appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
>>       <Append>true</Append>
>>       <file>logs/process.log</file>
>>       <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
>>
>>  <FileNamePattern>logs/process-%d{yyyy-MM-dd_HH}.%i.log</FileNamePattern>
>>          <TimeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
>>             <MaxFileSize>1MB</MaxFileSize>
>>          </TimeBasedFileNamingAndTriggeringPolicy>
>>       </rollingPolicy>
>>        <layout class="ch.qos.logback.classic.PatternLayout">
>>
>> <Pattern>%date|%level|%logger{10}|%msg|%throwable{5}%n</Pattern>
>>       </layout>
>>    </appender>
>>
>>
>> The thing is that in our production environment (HP-UX) and under heavy
>> load, logging was working fine for a time, and suddenly stop working.

>> From the status we see this:
