Issue

When copying files to this unRAID server via SMB after a few minutes the following happens:

 

• The web GUI becomes unresponsive
• Teracopy reports a network error has occurred
• Dockers no longer work (e.g I lose connection to my deluge deamon and cant connect via thin client or web UI)
• Browsing files in Windows Explorer through Windows 10 stops and freezes

 

When I stop the transfer through Teracopy everything works again within 10-15 seconds. I have tried different files to see if it somehow was related to a particular file but it hangs on different files and not just the same file.

 

I have tested this out 4 times over the last 2 days and it just happened twice in the past hour when trying to copy over files from a different server.

 

With this exact same setup a couple of months ago I was able to move 11TB of data over via the network with no issues with packets being loss or network errors according to Teracopy.

 

I have posted the diagnostics logs. Let me know if you need any additional information.

 

Thanks!

I have the same issue! And no answer at all!

But i had this since i.d.k. maybe unraid 4, and no solution at all.

Sometimes when copying files the server just became unresponsive, loses the network name and so on. After a couple of time it returns to normal and i can copy again.

It's just so frustrating! I always hope that an update could solve the problem but slowly i think this is related to my hardware setup. (Old Celeron, 4GB RAM, Onboard NIC, tried another 100% compatible PCI network card -> same behavior)
