Shaily, log4net is deliberately catch exceptions because it guarantees not to throw unexpected exceptions into the calling application due to configuration issue.
Also there are times when log4net may be working asynchronously to the calling application and therefore cannot throw an exception up the call stack to the calling application. log4net uses a plugin framework for error handling, each Appender has an ErrorHandler property which holds an IErrorHandler object. This is used to handle errors reported by the Appender. The default error handler used is the OnlyOnceErrorHandler and this writes the first error only (per appender) to the console. If you want to handle errors in a custom way all you need to do is to create your own implementation of the IErrorHandler interface and then set the ErrorHandler property on the appenders to use this new type, for example: <appender ...> ... <errorHandler type="MyErrorHandler, MyAssembly" /> </appender> Error handlers can only be set on appenders and there is no way of globally overriding the default error handler for all appenders.
