Leo,
I've attempted to reproduce this error, but I'm not having any
luck. Could you switch on log4net internal debuging (see
http://logging.apache.org/log4net/release/manual/faq.html#internalDebug
for details). This will produce a large amount of diagnostic output, but
the message you are interested in should read something like 'Setting
Property [Subject] to String value ...' Could you check that this occurs
only once, and that it is setting the value correctly?
Niall.
