% Administrative process for MGW NAT
|
|
|
|
% The administrative process takes care of re-loading the configuration
|
|
% after it has been re-parsed. This includes delivering a reload_config
|
|
% signal to all child processes of the supervisor. We don't do this
|
|
% inside the supervisor itself, as there might be an exception.
