Network interfaces cycles up and down everynight

[KevDog]

Regularly I receive an email from the FreeNAS system during the daily security run stating:

Code:

igb0: link state changed to DOWN
igb0: link state changed to UP

This has the unfortunate effects of killing any ssh session running within the various jails since they are bridging to the network card. Is there anyway to prevent this status change?

Here is the hardware in my system:

This should not be happening, particularly on the high quality equipment you're running.

When I occasionally see this, a reboot usually solves it. I'm not sure what the cause is. Could be the router needs a reboot, could be the NAS needs a reboot. But it's rare enough that I pay it no mind.

What troubleshooting have you done so far?

• Have you changed the network cable?
• Is your PSU operating correctly?
• Do you have any cron jobs?
• Is the network switch operating as it should be?

After doing some reading it sounds like a hardware issue, maybe not

In terms of troubleshooting steps, after some investigation I just changed the networking cable , so I'll see how that goes.
2. In terms of PSU operating correctly??? How would I know? Is there a method to troubleshoot the PSU? It's brand new which might or might mean anything. I've a multimeter however beyond this, I'm sure its different underload which could be at various times throughout the day.
3.Cron Jobs --- Yes I have many cron jobs, however the cron jobs are all being run in the jails. I don't have any cron jobs being run from the main system. Is there a difference from where the cron jobs are being run?
4. Network switch operating as it should??? Hard question there --- its a simple airport time capsule right now since a "real" switch is on the way. I'm not sure where to begin with this one.

I know I'm not helping my own cause with this one, however I'm at a loss kind of where to begin.
