I think it's something much more basic. I have a lot more experience on Solaris, so if you like, email me your /var/adm/messages file and I'll have a look. Some things you can check from the solaris box... ping -s default_gateway_ip see if you're getting any packet loss. netstat -nr see if you're noticing any network errors.
