Hallo!
Since 1/2 year I´m running a small notebook under Windows 7. When I looked in the task manager/resource monitor/network page, I found a amazing almost continous network activity. And there was no running up- or download of data. The total activity was 392Kb/s. Under Processes with Networkactivity I found : boincmgr.exe, PID 6156, transmit 26500 b/s, receiving 274 b/s; boinc.exe, PID 6480, transmit 277, receive 21927. All other few tasks have neglegible activity compared to this.
Under Networkactivity are listed the same tasks with the same activity.
Under TCP-Links ar listed the same files and the remark at both files IPv4-Loopback.
After halting E@H, the activity droped during 1 or 2 minutes to about 1/10 of the activity before. I had to shut down completely BOINC to stop all network activity.
For safety I let run a thorough check with my stadily updated virusscaner without any findings. What luck!
As there is also no activity on the LAN/WLAN, it must be some conversation of boinc with themself ??? But what for? Is it an artefact?
Is this also on other PCs?

boinc.exe manages and controls the science applications, for Einstein and any other project you're attached to.
boincmgr.exe displays information about the running processes in a way that you, the user, can understand: and it also passes back your instructions (if any).
The two programs communicate with each other via the internet protocol (TCP/IP), over the 'loopback' address 127.0.0.1
So, under normal circumstances, all that network activity never leaves your single PC. It's done that way, so that under slightly less normal conditions, that same 'Manager' on your PC can display, and control, the activity of boinc.exe on a completely different PC, over a network. BOINC is fully network aware, and needs no extra software to control additional PCs.
That's been the case with every version of BOINC, with all versions of Windows, and with all other operating systems as well - since well before you joined this project in 2005. The 'Manager' on your Windows 7 laptop could connect to and control a 5-year-old Linux computer on your home network - and vice-versa.
In short, it's normal, it's routine, and it's by design. Stop worrying about it!
Thankyou Richard for this
