Are you capturing log4net's internal error messages to see why its dying? Its
possible to capture internal errors and redirect them to
System.Diagnostics.Trace, send an email, etc.

Samuel,
I have not found an easy way to troubleshoot problems with Log4Net. I had
issues in the past with it but the only real way was to step into the
application's code and see where it was failing and what error was hopefully
throwing. However, I must said that in the exact way as you, this was not the
case many times as Log4Net decided to die silently without any notifications to
event log or anything like it. That would be nice to have so we get some
feedback but I have not found a way to do so yet. If you know let me know.
The only thing that I could think of is right permissions to the folder. The
ASP.NET impersonation needs to have read/write access to this physical folder
(Windows Explorer).
Other than that, I am afraid I do not have more to add.

I've changed my config according to yours but I still can't log. How could I
try to troubleshoot?
