I'd suggest that you change the program that's displaying the log file so
that it uses FileAccess.ReadWrite AND FileShare.ReadWrite when opening the
file. Otherwise, you won't be able to open the file as it already has a

This generally works fine with the RollingFileAppender but note that if you
use RollingFileAppender options that cause the file to be renamed, the
RollingFileAppender is automatically entered in the "can't rename the file
because someone else has it open lottery". (If you're using .NET 2.0,
there's a chance that adding Delete to FileShare in your program will
resolve this). Alternatively, using a FileSystemWatcher in your reading
program so that the file isn't open all the time might help.
