Subject TypeInitializationException in log4net.Util.LogLog
Date Fri, 17 Jun 2005 18:57:54 GMT
We've got a system set up where a Windows service kicks off a number
of sort of "sub-services", each in their own AppDomains.  Each
sub-service is responsible for initializing the log4net system within
it's domain.  Everything works fine on developer machines (running
Windows XP), but when we try to deploy it to a production machine
(running Server 2K3) we get a TypeInitializationException (stack trace
below).
We're using log4net 1.2.9 beta.

I'm trying to get some log4net debug logs, but the machine that's
producing the errors isn't directly under my control, so it's tricky.

Has anyone seen this sort of behaviour before?

The exception was: 

System.Reflection.TargetInvocationException: Exception has been thrown
by the target of an invocation. --->
System.TypeInitializationException: The type initializer for
"D2L.Mail.MailService" threw an exception. --->
System.TypeInitializationException: The type initializer for
"log4net.Core.LoggerManager" threw an exception. --->
System.TypeInitializationException: The type initializer for
"log4net.Util.LogLog" threw an exception. --->
System.NullReferenceException: Object reference not set to an instance
of an object.
