In addition I received this reply from Nicko Cadell that may help too: ----------- This is a known issue fixed in log4net 1.2.10. Please download the latest version from http://logging.apache.org/log4net/downloads.html
The exception is actually coming from an internal error handler. The Appender must have thrown an exception for this code path to be activated. The log4net.Util.LogLog.Error is used to log internal errors. The log4net.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 disable the internal error logging by setting the following <appSettings> in your application's .config file: <appSettings> <add key="log4net.Internal.Quiet" value="true" /> </appSettings> Cheers, Nicko ----------- Regards Ian Dykes - Software Developer Esendex Ltd 49 Stoney Street Nottingham NG1 1LX http://www.esendex.com Tel: +44 (0) 115 959 7962 Fax: +44 (0) 115 959 7966 Recommend Esendex's Business SMS service to a friend or colleague and you can earn up to £100 in High Street Gift Vouchers when they sign up.

I am using log4net with an asp.net 1.1 web service, and am writing entries to the log for every request. This is on a windows 2003 server, using iis6, and web gardening is turned on, so multiple instances of w3wp.exe are running and processing requests.

The I/O package is not thread safe by default. In multithreaded applications, a stream must be accessed in a thread-safe way, such as a thread-safe wrapper returned by TextReader's or TextWriter's Synchronized methods.
