Thanks for all the suggestions regarding this issue.

I have not been 100% able to verify that this problem is fixed due to 
the fact that the servers that always experience it are in production 
and we don't have a scheduled maintenance window that I can test with 
until 2008. However, on the systems I did test with that are not yet in 
production, the suggestions work fine.

If anything changes due to later testing, I will repost the summary.


1. Use a /platform/sun4u/kernel/drv/ce.conf file instead of ndd to set 
up the interface
2. There is also the potential for an openboot firmware issue, but I 
have not investigated that yet
3. Don't mix auto/auto with hard wired (not applicable here, but good 
advice all the same!)

Thanks to:

and George
