In our environment at least, this seems to be caused by plugins from Native Instruments (Kontakt, Absynth, FM8, Reaktor, Massive, Battery, Guitar Rig, and RC48 reverb plugin). It appears that in recent versions of these plugins, an option called Usage Data is enabled and that option is causing the plugins to try and connect to (presumably) Native Instrument servers. For some reason, the plugins don’t seem to give up when a connection can’t be made, perhaps they just keep retrying forever, we don’t know.
