Jitendra,

as I can see, there are only 2 options:
- do not use (Daily)RollingFileAppender
- or use different log file names for different processes.

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

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

Regards,
Jitendra

Hello,

I had the same problem with the "RollinggFileAppender" in log4cxx 0.9.7 The
reason was, the log file was opened in a second process. this prevented the
first process to rename the file and the file was truncated to zero length
in its trial to create a new empty log file (after the rename)

Hi,

I am using Log4Cxx on Windows. 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>

Jitendra
