freebsd stable - May 2003 - What the???? Is there a Doctor in the house? Help

Ok  do not know what is causing this problem and would
appreciate some help in tracking down the cause.

FreeBSD 4.7

System runs fine for maybe a week and then all networking
stops - without warning. I do not know anyway of  persuading
it to resume networking without rebooting.

Does anyone have some useful suggestions on how to diagnose
the cause?

The more details you post about your setup the more likely someone will be 
able to suggest a course of action.

Also, you are best off posting this question to questions@freebsd.org as 
its more of general question/issue you have rather than one that pertains 
to -STABLE.  Also, have a look at http://www.lemis.com/questions.html which 
explains what you need to post.  Otherwise people will not be interested in 
guessing what your setup is.

Had this problem some time ago. A process got killed.
Do a ps -ax right after rebooting and also when the network isn't working 
again. Compare these two and look for processes that aren't there any more.

Also look at the console. When I had the problem for the first time, I got 
some error messages saying that there isn't enough buffer space or so.
This could be another possible cause.

You said you had a XXXX networking card, so that's probably
the problem.  Try this patch on if_XXXX.c:

+XXXXXXXXXX
-XXXXXXXXXX

(it's a unidiff).

Really, you need to provide us with at last the name of your
networking card.

Also, you should try to ifconfig down the interface, and then
ifconfig it back up, in case it's a lost interrupt or something
that needs a timer to correct (doing the ifconfig's will reset
the card).
