In addition I received this repl= y from Nicko Cadell that may help too:

-----------
This is a know= n issue fixed in log4net=20 1.2.10. Please download the latest version from http://logging.apache.org/log4net/downloa= ds.html

The exception is actually coming from an internal error = handler. The Appender must have thrown an exception for this code path to b= e activated. The=20 log4net.Util.LogLog.Error is used to log internal errors.

The log4ne= t.Util.LogLog.Error writes to the console, and the System.Diagnostics.Trace= handler. It looks like Console code isn't working correctly.

This is not recommended but If you must use log4net 1.2.9 then you can disa= ble the internal error logging by setting the following <appSettings>= in your application's .config file:

<appSettings>
<add = key=3D" log4net.Internal.Quiet" value=3D"true" /> </appSetting= s>

Cheers,
Nicko

Subject: Uncaught exc= eption:=20 System.IndexOutOfRangeException

I'm using log4net 1.2.9 and got thes= e uncaught exceptions thrown from my application causing it to crash this p= ast weekend:

System.IndexOutOfRangeException: Probable I/O race cond= ition detected while copying memory.

I am using log4net with an asp.net 1= .1 web service, and am writing entries to the log for every request. This i= s on a windows 2003 server, using iis6, and web gardening is turned on, so = multiple instances of=20 w3wp.exe are running and processing requests.

Here is the full stack= trace:
