If its only on one CAS/HUB then either clients is only accessing this server or this server is only accessing another system that cause this events.
You can turn on CAPI2 logging to get more clues.
Open Eventviewer, goto application and services logs/Microsoft/windows/CAPI2, right click on operational and select enable log. This will get you info about whats going on. Dont forget to disable CAPI2 logging when done.
