Hello group:

I have a 5.0.6 server with Merge 5.3 installed that was performing just
fine. Now I have a situation where sporadically the network tcp traffic
freezes. Serial connections are fine. System console is fine. Cannot ping
other computers and vice-versa. tcp stop/start does not clear the
situation. Using double vision, I can attach to the tcp telnet sessions and
close the running programs that are character based. After a reboot of the
server, all is well for a while. During shutdown there are two complaint
messages for which I do not remember the text, and I believe these to be
from attempts to close a share to another OpenServer computer.

The network card was replaced.

Any ideas are appreciated.

Thanx
Ron

Ron,

first of all make sure the above system is patched with the
latest/greates patches available from SCO:

http://www.sco.com/support/ftplists/osr5list.html

Next, when the problem arises, are you able to stop/restart the network
device by using the "nd(ADM)" command ?

Did you notice anythin unusual under /usr/adm/syslog ?

What does "ndstat -l" report ?

Best,
Roberto

Two conditions I've seen this:.

- Cheap network cards - why people put $10.00 cards in important servers is beyond me..

- Not current driver (see
ftp://ftp.sco.com/pub/openserver5/drivers/

The card is a 3-Com 3C905-TX. I have other machines using this card with no
problem.

Driver is the one as supplied on the 5.0.6 install disk.

The computer has worked fine for a year.

Do you have the same license running on multiple servers on the same
lan? Have you added a new server/nic and have a MAC collision?

You might try removing the 100Mbps card and installing a 10Mbps unit
(the highest speed that used to be supported by the former software
company, SCO). Openserver becomes very unstable when attempting to
handle moderate volumes of network traffic (we experienced severe IO
errors and disk corruption when attempting to use OS as a mail relay
for an office of 23 people). Using a slower card will give the kernel
a chance to handle the load. I believe you can purchase a licence for
an "enterprise" level kernel or something from SCO that will handle
fast 100Mbps speeds.

You might try getting at least half a clue..

Disk corruption blamed on a network card?

No wonder people like me can still make a living..

No, I don't think you have even that much. See

Wrong driver. Get the right one from the ftp site.

No and no ( I do not think so as the card was swapped).
