wired log4net problem: it refused to log anything.

[Cheng <ch...@gmail.com>]

I've been using log4net for a while and it works for all the project.
But I met a problem today that log4net refuses to log anything in an
asp.net  application.

here is the config:

	<configSections>
		<!-- Register a section handler for the log4net section -->
		<section name="log4net" type="System.Configuration.IgnoreSectionHandler" />
	</configSections>

	<!-- This section contains the log4net configuration settings -->
	<log4net>	
		<!-- Define some output appenders -->		
		<appender name="RollingFileAppender"
type="log4net.Appender.RollingFileAppender">
			<param name="File" value="d:\\logfiles\\Log.txt" />
			<param name="AppendToFile" value="true" />
			<param name="RollingStyle" value="Size" />
			<param name="MaxSizeRollBackups" value="10" />
			<param name="MaximumFileSize" value="1000KB" />
			<param name="StaticLogFileName" value="true" />
			<layout type="log4net.Layout.PatternLayout">
				<param name="ConversionPattern" value="[%d{MM/dd
HH:mm:ss,fff}][%-5p]:%c{2}.%M():[%x] %m%n" />
			</layout>
		</appender>
	
	<!-- Setup the root category, add the appenders and set the default level -->
	<root>
		<!--ALL DEBUG INFO WARN ERROR FATAL OFF -->
		<level value="ALL" />
		<appender-ref ref="RollingFileAppender" />
	</root> 
</log4net>

I've assigned "full control" permission to ASPNET account for d:\logfiles\
when I tried to trace into log4net, I found that the the function
IsDisabled(Level level) in Hierarch.cs line 447 is always return true
(because the Configure variable is true in line 454).
Can't figure out why? Please help.

btw: Other asp.net application still works fine, there are logging
into the same directory with different file name. the config above is
copied from a working asp.net app with only change of the logfile
name.
