Hello, this is my first post in this forum

 

My problem is that after some idle time, my server cannot be reached. Not with SMB shares nor SSH or through web interface.

At the first time I had this issue I pushed the power button on the server and the system went down properly, so it wasn't frozen. After power ON again, it worked for 2 days without any problem. Of course the log mirror to the flash drive was turned OFF so I did not know what the problem was.

 

Today I lost the connection again but instead of resetting the server again, I tried to unplug and plug the LAN cable. And tadaaam, I can reach Unraid again!

I checked the log and found this:

Do you have any idea what went wrong with the ethernet at 09:16:57 ?

If it doesn't help I would try with a different NIC.

Thanks, I"ll give it a try.

What NIC is fully supported and no issues at all, even work with C-state >C3?

Intel is usually better, but don't know about C-states.
