See below for the debug message.
Yes, I have log4net watching the config file, which I assume is the reason it starts \
working when I re-save the config file.
I've seen the SMTPAppender and RollingFileAppender have this issue, the console \
appender doesn't seem to have the problem.
I can try the latest log4net to see if the issue re-occurs.
Michael

Michael,
Do you know which of your appenders you have experiencing this issue
with?
If you have log4net watching the config file and modify the file then
logging configuration will be completely reloaded, which appears to be
resolving your issue.
If you enable log4net internal debug do you get any error messages from
the appenders when they stop writing?
http://logging.apache.org/log4net/release/faq.html#internalDebug
Can you repeat the issue with the latest version of log4net?
http://logging.apache.org/log4net/downloads.html
Cheers,
Nicko
