Automatic reloading of changed configuration files:
To alleviate this performance hit a bit, init_and_watch() can be configured to listen for a Unix signal to reload the configuration instead: 
    Log::Log4perl->init_and_watch($conf_file, 'HUP');

[download]
This will set up a signal handler for SIGHUP and reload the configuration if the application receives this signal, e.g. via the kill command: 
    kill -HUP pid

[download]
where pid is the process ID of the application.
Log::Log4perl::Config::Watch:
SIGNAL MODE

Instead of polling time and file changes, new() can be instructed to set up a signal handler. If you call the constructor like 

    my $watcher = Log::Log4perl::Config::Watch->new(
                          file    => "/data/my.conf",
                          signal  => 'HUP'
                  );

[download]
then a signal handler will be installed, setting the object's variable $self->{signal_caught} to a true value when the signal arrives. Comes with all the problems that signal handlers go along with.
