This isn't making very much sense. It looks like you're trying to connect from your server to port 113 on another server. Most likely you have some misconfigured application on your server. Unless you are indexing the application logs (and the logs themselves show connections), Splunk isn't going to be much help.
Best bet will be to do (if you have a *nix) box, is to do lsof | grep 113 - this will tell you what process is trying to connect.
