Hi Jürgen, Thanks a lot.
I cannot use the second option. I have a java application that maintains a pool of these processes. As per the pool, the processes are launched and destroyed to maintain sufficient number of processes in the pool to serve the application. Moreoverall processes are instances of the same executable. Hence they write to the same log file. Regarding the first option, can any other Appender be used to avoid this problem? I am not keen about RollingFileAppender as far as the log is generated correctly and the older files are backed up.

We decided to choose the second option and now it works well.

Exactly, I have the same problem. I am accessing the log file from multiple processes. But how to overcome this?

I always get the following error ------------------------------------------------------------------------ ----------------------------------- Failed to rename [C:\app-name/logs/event-handler.log] to [C:\app-name/logs/event-handler.log.2005-11-28]. ------------------------------------------------------------------------ ----------------------------------- Due to this error, in order to continue writing log, Log4Cxx overwrites the old log file. Thus I lose the old log. I am using DailyRollingFileAppender and my config file is as given below <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "./log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"; debug="false"> <appender name="APP_LOGFILE" class="org.apache.log4j.DailyRollingFileAppender"> <errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler"/> <param name="File" value="${APP_HOME}/logs/event-handler.log"/> <param name="Append" value="true"/> <param name="Threshold" value="warn"/> <!-- Rollover at midnight each day --> <!--<param name="DatePattern" value="yyyy-MM-dd"/> Does not work--> <param name="MaxFileSize" value="25MB" /> <param name="MaxBackupIndex" value="10" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%d %-5p [%c{1}] %m%n"/> </layout> </appender> <root> <appender-ref ref="APP_LOGFILE"/> </root> </log4j:configuration> Regards, Jitendra
