I am testing a simple app that consists of one exe and 3 dlls. I am trying to set it up so that each project (the exe and each dll) have their own unique static logger, config file, and output file. When I run, I get the desired logging in the desired locations for the exe and the first dll that is called. But for the second and third dlls, I get the following errors. Any ideas as to what is causing this?

Thanks!
Mark

Mark,

Can you send over your config file, and also can you reproduce this
situation with internal logging enabled:

Here's the config file for the exe (form1_log_config) and the three dlls.

Here are the config files and the output from having internal debugging enabled.

Mark,

How are you loading the config files for the exe and dlls? Are you
calling the XmlConfigurator programmatically? And if so when?
Are you explicitly calling the LogManager.Shutdown method at any time?
Are the log4net:ERROR messages printed at or just before program exit?

Nicko

In the constructor of each, I am calling:

XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(@"C:\arc\sample clients\arc_prototype\form1_log_config.xml"));

with the file being different for each.

I am not calling LogManager.Shutdown() anywhere in the solution.

The ERROR messages are printed during runtime, as each dll is tyring to log

Mark,

Your 4 config files are being loaded into the same space and they are
being merged together as they are loaded. As they are watching their
source files they are also being reloaded in unpredictable orders.

As a first option can you try removing all the <appender-ref> elements
from the <root> element in all of your config files.

Is your intention to have completely separate logging configurations for
each or your dlls? If so you can specify a named log4net repository for
each assembly. Add the RepositoryAttribute to each assembly with a
different name:

[assembly: log4net.Config.Repository("assembly-name")]

Cheers,

Nicko
