IOException in Category.error()

[Ole Bulbuk <Ol...@ebp.de>]

Hi,

when the underlying disk is full (which will happen quite frequently for our
software), Category.error(...) throws an Exception:
log4j:ERROR Failed to flush writer,
java.io.IOException: Auf dem Gerät ist kein Speicherplatz mehr verfügbar

I think this is a undesired reaction. An error in an error handling system
(like logging) is usually something really bad. It would be nice if the log
message would have been written to standard error (System.err) instead.

Regards,

Ole
