Hi Andy,
Looks like the MaxBackupIndex is hardcoded to 12 for log4cxx as the
renaming of all the files is required for every rollover.
Here is the email form Dale sometime back on the similar issue.
Hope this helps

12 is a hardcoded limit because this requires renames of all backup
files which is expensive .

Subject: Problem with RollingFileAppender only retaining 14 files.
Hi,
We have been using log4j in our Java applications for some time and they
seem to work fine. We have a single application written in C++ which is
now
using log4cxx 0.10.0.
I have setup an appender as follows
<appender name="file" class="org.apache.log4j.RollingFileAppender">
<param name="Threshold" value="DEBUG"/>
<param name="File"
value="e:/iqbonds_uat_egb362/logs/CurveBlender/CurveBlender.log" />
<param name="Append" value="true" />
<param name="MaxFileSize" value="10MB"/>
<param name="MaxBackupIndex" value="50"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p %c{1} - %m%n"/>
</layout>
</appender>
It seems to work fine except it is ignoring the MaxBackupIndex parameter
because once it gets to 13 files it deletes the oldest files. So I have
files like app.log, app.log.1 ..... app.log.13 but when it rolls it
deletes
app.log.13.
Any help would be appreciated.
Thanks
Andy
