Weird connection requests to xxxx.wdf.sap.corp in the ICM trace

Maybe you have seen one or two systems that for whatever reason fills up your wonderful log with totally useless information.
One of the more annoying ones, is when SAP accidentally leave stuff in place that should never have gone into a customer system. One of these is when you see messages like:

[Thr 139801848358656] Sat Nov 19 01:19:34 2016
[Thr 139801848358656] *** WARNING => Connection request from (8/9/0) to host: hs2086.wdf.sap.corp, service: 2000 failed (NIEHOST_UNKNOWN)

These will populate your ICM logs, and clog them up forever if you dont do something about it.

Now, the smart person might quickly realize that these are http connection requests (why else would they be in the ICM ?), and you may even have guessed (either based on the name or the port) that this is a content service of some kind. But when you go to transaction OAC0, there are tonnes of SAP standard stuff in there. Which one is it that you need to get rid of ?
Well, fortunately, the answer is simple. Go to transaction CSMONITOR, fold out the "ContentServer", and keep folding out, untill you see the names of the archivelinks. (in a netweaver 7.3, it is usually named A2 and B2)
then simply go to transaction OAC0 and mark and delete these two offenders
