Hi guys, I'm getting alot of In/Out errors on my LAN interface as you can see on the screenshot, its not something that happens all the time but it does happen at times and I'm trying to understand what triggers it, could it be a bad Ethernet card? I'm using an ADMtek card, I've never used such a card before so I don't know good or bad it is. Should I be worried about the errors or its something I can ignore! Regards Cosmas. Attachments:

That should be zero or near zero. try another cable, switch port, switch or another NIC.

Thanks Roy, will check all those then report results.

It should be zero. But what else is happening when it happens? Some cards are very CPU dependent, and if you have an older Geode and use a lot of VPN, for example, it can overload.
But cable and switch port are a good start.

I'm not using VPN...I've noticed that this happens when there is alot of upload traffic, I'm using 833mhz and the CPU usage is always 0 to 3% even when this is happening. so maybe the card?

It is inbound errors, so it is on the upload side. It could be a bad nic, cable, port or switch. It could also be a duplex mismatch if the LAN switch is set for half duplex. There is also some traffic that can cause packet errors, but it is uncommon. What do the logs show?

unfortunately I lost the earlier logs, system rebooted. But the issue has just re-occurred again this time when changing the cable and I've grabbed the logs as you can see in the screenshot. Attachments:

Well, on the plus side, dc is the Intel network driver, so you actually have a good chipset. Perhaps on a cheap card, but they used the chips from Intel. Are you using Device Polling on the System -> Advanced page?
If flipping that does not help, look to a hardware problem. That watchdog timer could be a problem, or just poorly implemented rate limiting. 3coms are notorious for throwing them. The Link up and down is the real issue.

swap the WAN and LAN assignments (Interfaces: Assign network ports) and see if the problem follows the NIC.

I'm not using the Device Polling option, will try it and see, will also try what Roy has suggested I think that will tell if its the card or something else.

For what it is worth, from the first screendump it seems that the troublepackets are less then 0.07 precent. We used to see the same thing on an old box, Pentium with 10Mb/s cards. It never caused any performance issues. (Yes, Internet in this part of the world comes at 3 or 4 Mb/s.)
Minor packetloss has always been here and always will be, not something to worry about.
Only when the ISP swapped the Motorola modem for a CBN modem/router did this become a problem. The new box did not play nicely with the old NIC's and packetloss went up to more then 30%. Replacing the CBN box with a Huawei modem/router solved the problem.
And our customer is still running m0n0 on an old Pentium based system. That is what m0n0, and hopefully SmallWall are made for.

Right now my build machines are old Wyse Cx0 terminal servers. I want to make sure in the drive to support new hardware (Like Atom motherboards and nics) we don't lose the old ones.

His link is going up and down. That's not normal! His NIC is running 100Mb full-duplex not 10Mb half-duplex! Packet loss is not the same thing as input/output errors! He has a problem that needs to be addressed.

So, I changed cable three days ago, the interface has reported only two errors so far, even using all my upload capacity most of the time has not brought back the errors. I'm going to watch it for another week or so but for now it seems it was a bad cable. Thanks guys for all the help and advice.
