Topic: Connection to the NIC

[Michael Laursen]

every now and then my server stops responding to any trafic on my nic, result reboot the box, i have replased every hardware part in the machine but no luck.

my system is a dual 1000, 1GB ram, 40 gb hd, tnt2, asus cuv4x mainboard.

there is no entry in the log files that says something is wrong..


does anyone have an idea what causes this ?

I am sure you have replced the nics but I find that nics by Realtek seem to solve most issues with the network.

Did getting realtek cards help?

I've been having the exact same problem.  External network goes down, no errors in the logs, and restarting services doesn't help.  I restart the whole server, and it works fine again.

I also have a dual 1000 PIII, 30 gig hard drive, Abit mobo, and 1 gig RAM.

I have 3com network cards in there right now.  The one that seems to be failing is a 3com 3c905c -tx.

Hi Michael

Probably you already know this, but anyway.

I had the same problem in 2 different situations,
in the two the server freezes for no reason, nothing in the log
and a cold boot solve the problem momentarily.

1st case was a PII 300 - 128 Mb 10G hd 2 NIC 3C905TX-B

The story resulted to be that the 2 NIC 3C905TX-B, don't know why,
doesn't like each other , so I get a newer 3C905Tx-C (that uses
a different driver) and replaced this for one of the TX-B and worked
excelent, and still is working (using it right now).

2 nd case PII 400 - 256 Mb 20G hd NIC 1: 3c905TX-B, NIC 2:
Realtek 8139.

This 2nd case resulted to be a mobo story, I couldn't figure out
what, but a replacement of the mother board solved it,
the weird part is that the replaced motherboard work good on
windows, but SME don't like it (a soyo 6VBA if i remember correctly).

may be this give you some idea.
also: did you try to run SME only with 1 processor running?.

I hope to help something

see you

I've seen the same problem since 5.1.2.

I'm running on a dual P200MMX.  I was originally using two Intel Pro/100 S cards but now am using one Pro/100 S card (internal) and a Tulip/21041 10baseT (external).

I've never had to reboot though.  I eventually get a response -- after a few minutes or so.
