For what is worth, I checked our environment and see the same behaviour - incoming connection every 3-4 mins, so my guess is that it is “expected” (all I can think for myself, is that is the account it uses for all the VM manager config change actions; test results; etc, so maybe they purposely made it “refresh” those every 3 mins - if you change/submit VM manager test and refresh BFI UI in a few mins, you see the results of the test - you don’t need to wait until next full data import to see the results, right?) but if you want to get to the bottom of it my suggestion would be to open a Support case and have L2/L3 check it against intended design.
