CG-Referrer plugin displays bot from own server?

In the middle of last week, my CG-referrer list started showing an almost constant and unstoppable list (pinging?) from an address on the server where my site is hosted. The address is always https://[…….].net:2086/scripts/srvmng. Has anybody seen this before? It seems like some kind of indexing from the server, but it’s very annoying, since it drowns every other referrer. I already asked my server-administrator, but he doesn’t seem to know what it’s about.
Two days after the problem started, i upgraded wordpress and the cg-plugins to the latest versions, but the strange referrer remained.
Any ideas?
