my cron scripts that use FTP are failing "unable to locate server" email is backing up in the mail queue and not going out at all for the last few days. if I ssh into the server and try most network stuff -- like whois, ping (using a domain name), host, etc, I get a network related error much like the FTP error above. The ISP seems to think the server needs to be cold rebooted, but it's been more than 48 hours and they still haven't rebooted the server. I've restarted it from ssh, but it doesn't seem to help. The firewall seems to be okay, I even reset the rules and still no go. Any ideas what it could be, or if I can do anything about it without a cold restart?
