I have 3 rigs on Asrock h110 BTC+ nvidia based (1070 + 1060) on different PSU's and connected to different routers. All of them has very unpleasant problem: once or twice or thrice per day the system hangs and hangs the entire network. This happens only on nvOC, on smos or on ubuntu 16.04 - ok about 2 days. Tried: disable (and remove) dhcp, another router, disable network manager, usb-lan but problem still here. Any thoughts?

You say "the system hangs and hangs the entire network" yet you also say you have 3 rigs. Do you have any idea which system is responsible for a particular "hang"? Also, how do you fix the hang? You also mention disabling usb-lan so how are the rigs connected to the network - wired, wireless, or?

You may want to look for errors/issues in in each rigs /var/log/syslog.

Rigs are in different places but with the same symptoms. Connected by wire. Hangs only can be fixed by reset button or power switch.

Ok. Thanks for the clarification. What do you see in /var/log/syslog at around the time of the hangs? There should be some clues in there.

Usually when the whole network hangs its a sign of network, mac address or ip conflict.

I had same issue once with my home NAS, when I connect its both lans to switch all my network was freezing.
I couldnt even connect to router, until I found the problem

and what was the problem ?

Synology updated firmware and after that I can not connect both lan ports to same network any more
5-10 minutes after I connect both my whole network freezes.

thanks for replying
