This happened to me on 130 and later. Sometimes I would lose network connectivity and the only solution is to do cp /etc/nsswitch.dns /etc/nsswitch.conf
This always happens right after booting system. This happens when I'm using DHCP and when I'm using fixed IP address. Also when I copy nsswitch.dns, the system freezes for a second every 3-4 seconds until I restart it. After restart everything is fine. I don't know what is causing this issue. Does anyone have any idea? -- This message posted from opensolaris.org
