Hi I have the following log backup.xml <configuration scan="true" scanPeriod="30 seconds"> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>/opt/apps/scms/logs/scms.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- rollover daily --> <fileNamePattern>/opt/apps/scms/logs/scms-%d{yyyy-MM-dd}.%i.log.gz</fileNamePattern> <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"> <maxFileSize>100MB</maxFileSize> </timeBasedFileNamingAndTriggeringPolicy> </rollingPolicy> <encoder> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS,PST} [%thread] %-5level %X{user} %logger{0} - %msg%n%xEx{3}</pattern> <outputPatternAsHeader>true</outputPatternAsHeader> </encoder> </appender> … And this use to work fine.. Since 10 days ago I deploy my application and since then instead the files being rolled on daily bases or if they reach 100MB I have 10s of smaller than 1MB files.. One or two of the log files each they are 1.2 or max 1.5 MB.. I have made sure that this configuration is being used by changing the maxFileSize to <maxFileSize>10KB</maxFileSize> and logs are less than 10KB .. Anyone out there has seen similar issues or can give me a clue what I am doing wrong… Thanks Parimah Mehrrostami
