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.
Basically:
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:
