Web Hosting Talk : Web Hosting Main Forums : Dedicated Server : Server is down very often.

When I checked the message log, here is what I see:
May 28 11:43:33 dedicated kernel: NETDEV WATCHDOG: eth0: transmit timed out
May 28 11:43:35 dedicated kernel: e1000: eth0: e1000_watchdog_task: NIC Link is Up 10 Mbps Half Duplex

The server has pretty high traffic, alexa 17,000
512M ram, celeron 2.8 G

Try:

/sbin/mii-tool -F 100baseTx-FD

What's this for?

[tsj5j]

Your server's network card is currently set to 10mbps half duplex.

This means that the traffic going OUT + IN must not exceed 10mbps.
So you can use 10mbps OUT / 0mbps IN, 5mbps OUT / 5mbps IN, etc.

That command sets it to 100mbps full duplex.
That means you can use 100mbps OUT / 100mbps IN simultaneously.

Wouldn't the host / data center regulate port speed so yuo simply can't turn a 10mbps port into a 100 mbps one?

[tsj5j]

They can control your speed by configuring the switch to limit you.

But I believe the half-duplex is a configuration mistake.
Its rather uncommon nowadays for dedicated providers to do half-duplex.

yes. tsj5j is right, they can limit your transfer rate through the switch port, and since u have high traffic, so when users are requesting more page through that link, i will either get very slow or a request-timed-out message will appear on the browser, i think you should upgrade into 20 Mbps

[mealto]

Here was the suggested syntax: /sbin/mii-tool -F 100baseTx-FD

Aren't 10baseT and 100baseT different than setting half and full duplex settings? If I am reading the above correctly, it was suggested to try and turn port to 100mbps PLUS adjusting it to full duplex no?

[tsj5j]

I am assuming, of course, that the provider made a gross error in configuration.

If they were to be right about the port speed, try :

/sbin/mii-tool -F 10baseTx-FD

Do not change your network card's port speed without asking them first.

If you force it to 100 as some have suggested above, and the provider's side is set to 10, you will lose connectivity.

And they might charge you to physically login to your server and fix it.

However, yes, it should be full duplex, not half. Still, a mismatch would not cause the network card to "timeout". It would just cause it to drop a lot of packets.

What version of the Linux kernel are you using? Older kernels had issues with Intel network cards suddenly timing out... we used to see that many years ago with older distros.
