We have been using Linux (Caldera version, Kernel 1.2.13) for about
four months now. We have been using it as a mail server basically.
We call in to our ISP with UUCP and upload/download mail.
The local network is comprised of several NT servers, the Linux server,
and Windows'95 clients. Protocols running are IPX/SPX (a la Microsoft),
and TCP/IP. The clients retrieve and send mail using Microsoft
Exchange, which uses pop and smtp. We are using static IP numbers.
Everything was running fine until several weeks ago when we had some
network problems with one of the NT servers (changing from coax to TP).
Now it seems like the Linux several TCP/IP times out.
You cannot ping it, mail cannot be collected or sent to it. To fix it all
that seems to be needed is to ping several addresses from the Linux
server. This seems to re-establish the network.
When it disconnects, the /var/log/messages file has these messages
written to it:
Jul 10 14:57:20 lxkraus kernel: eth0: mismatched read page pointers 4c vs 5d.
Jul 10 14:57:20 lxkraus kernel: eth0: mismatched read page pointers 4c vs ff.
Jul 10 14:57:20 lxkraus kernel: eth0: unexpected TX-done interrupt, lasttx=20.
Jul 10 15:12:36 lxkraus kernel: eth0: timeout waiting for Tx RDC.
Any help, ideas would be appreciated.
