WinDbg is constantly reconnecting or just spamming debug output windows

All worked fine. Than without the obvious reason WinDbg started to spam my debug output window with messages:
Connected to target 10.10.11.80 on port 50001 on local IP 10.10.1.202.
Shutdown occurred at (Tue Feb 2 15:16:37.786 2016 (UTC + 2:00))…unloading all symbol tables.

I got it every second. Looks like it loses connection and reconecting. Debuging works fine, just this annoing message. Any ideas how to fix? ( I am using network debugging. Restart doesn’t helps.)

Your test machine and debugger machine IP is different sub-net.
please try maintaining 10.10.1.xxx series in both machines.
