multiple socket appenders

["Reid, Khalid" <Kh...@BellSouth.com>]

We are re-architecting our environment to be fully clustered and fail
safe.  With that in mind, we need some facility to ensure that our
application logs are also fail safe and contain logs from activity on
all clustered boxes.  The solution I am investigating is each box in the
cluster will log to multiple socket servers (1 socket server running on
each clustered box) therefore ensuring that the logs on all clustered
boxes are captured and also ensuring that if one of the boxes goes down,
our field support guys can just check one of the other boxes (since all
boxes contain copies of the same log files).

The problem is that appender BENCHMARK1 and BENCHMARK2 may or may not
receive the log messages.  Can someone help me out?

I'm not sure what you are asking.  Are you saying that you are  
observing a problem in log4cxx where the BENCHMARK1 and BENCHMARK2  
appenders are failing to send the messages and you are wanting help  
analyzing the problem?  Are you concerned about the scenario where  
the receivers are not working properly and want to design some fail- 
over strategy?  Or something else entirely?
