Re: Logging truncates the file at noon

Hi Baron:

I am using the RollingFileAppender as well, and don't have any issues. The only 
thing I could see
with your configuration that is different than mine is the datePattern 
parameter that you are
using. Here is my configuration for the RollingFileAppender, which seems to 
roll over at midnight
and does not truncate. I also use a filter, but that should not make a 
difference.

                <appender name="DEBUGRollingLogFileAppender" 
type="log4net.Appender.RollingFileAppender">
                        <file 
value="C:\\Scratch\\SOW\\WfStatusTrackingClient\\DEBUG.log" />
                        <appendToFile value="true" />
                        <datePattern value="yyyyMMdd" />
                        <rollingStyle value="Date" />
                        <layout type="log4net.Layout.PatternLayout">
                                <conversionPattern value="%d{yyyy-MM-dd 
HH:mm:ss,fff} %-5p - [%t] %c: %m%n" />
                        </layout>
                        <filter type="log4net.Filter.LevelMatchFilter">
                      <levelToMatch value="DEBUG" />
                    </filter>
                    <filter type="log4net.Filter.DenyAllFilter"/>
                </appender>
