Subject RE: intermittent appender failures
Date Wed, 24 Aug 2005 11:16:19 GMT
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?

Cheers,
Nicko
