Are you doing your configuration in the constructor of a non-local 
static variable?  Since there is no guarantee on the order that these 
initializers occur, there is the possibility that the configuration is 
being interpreted before the available appenders have added themselves 
to the map used to resolve the configuration file.  In that case, you 
need to find some way to defer configuration until all the non-local 
static variables have been initialized.
