We have a production 3020 VPN Concentrator that started having an issue a couple of days ago. When we make a change, we receive a popup box saying Unable to Save Bad Value Error. We have restarted the concentrator once, and found that it did allow us to save once. Now we are back to the error. Since it's a production box supporting many tunnels, restarting is very disruptive, and we loose all of our changes. Any ideas on what would cause this error and how to fix it?
