Manuel Spezzani commented on LOG4NET-683:
-----------------------------------------
I'm experiencing exactly the same issue. By looking at log4net internal logs I
see this:
{code:java}
log4net:ERROR [UdpAppender] ErrorCode: WriteFailure. Unable to send logging
event to remote host <redacted> on port <redacted>.
