RollingFileAppender isn't a database. If you have multiple programs logging to the same file
I suggest using another appender.

Hi, 

We are having 10 programs which are rolling into same log file namlely
"logger.log". 

Below is configuration of RollingFileAppender which we are using : 
  <appender name="RollFile" type="log4net.Appender.RollingFileAppender"> 
    <threshold value ="ALL"/> 
    <file value="C:\logger.log" /> 
    
    <appendToFile value="true" /> 
    <maximumFileSize value="1GB" /> 
    <staticLogFileName value="true"/> 
    <maxSizeRollBackups value="5" /> 
    <datePattern value=".yyyy-MM-dd-tt".log""/> 
    <rollingStyle value="Composite" /> 

    
    <layout type="log4net.Layout.PatternLayout"> 

      

    </layout> 
  </appender> 

Our rolling based on date is running at every 12 hour span means at 12 Noon
and 12 Midnight. Now what is happening when multiple programs try to log
into log file at the same time when rolling happens means at 12
noon/midnight, then size of file getting rolled is becoming very small
compare to original file size(i.e Suppose logger.log is around 1 MB at 12
noon, when rolling happens the new rolled file which is get generated is
around 3 KB or somewhat). So, almost data get lost due to this. This is
basically happening when multiple programs try to log into log file at the
same time of when rolling happens(means at 12 noon/midnight). 

Please revert back to us on this ASAP as its very important us to go ahead.
