Hi,
I am using log4Net v1.2.13 in a .NET 4 C# project. I have setup a RollingFileAppender to roll on size. My aim is to keep appending to a log file and roll on size. I need to maintain all the previous log files. But I found that every time my application restarts all the log files after the 2nd log file that was generated in the previous run get overwritten. For testing purposes I set the rollover size to 3KB. Below is the appender configuration. <appender name="RollingAppender" type="log4net.Appender.RollingFileAppender"> <file value="logs22\myFile_d.log" /> <appendToFile value="true" /> <rollingStyle value="size" /> <staticLogFileName value="false" /> <maximumFileSize value="3KB" /> <countDirection value="1" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value = "%date %-5level [%logger] %message%newline%exception"/> </layout> </appender> On first run of my application the appender rolls the log files on size. It created 3 log files myFile_d.log.0, myFile_d, myFile_d.log.2. Each log file was around 5KB before getting rolled. When I ran the application again, this time instead of creating a new log file myFile_d.log.3, Log4Net started overwriting the second log file that was generated earlier (that is myFile_d.log.1 was overwritten). It then proceeded to overwrite myFile_d.log.2. I updated the config and included <maxSizeRollBackups value="-1" />. This time log files were rolled without any overwriting of existing files. A similar scenario described in this issue tracker - LOG4NET-378. The bug has been closed with resolution fixed in v1.2.12. I would appreciate it if somebody could confirm the following points 1. What is the default value of maxSizeRollBackups if it is not mentioned in the config file. I could not find this in documentation for this property. 2. For the scenario that I described is expected to include maxSizeRollBackups=-1 in the config file? Thanks and Regards, Mohkam Singh
