I upgraded to v9 over the weekend. Everything seemed to come up okay and I received no errors during the upgrade process. Today I noticed we were not getting any new data. I checked the polling engine status and it shows it is up and running. The web engine shows all the devices fine, but the system manager shows no devices even if I add a new one. When I open the database directly all my nodes are still listed. I tried the configuration manager and repaired the installation and that has not worked. I rebooted both the DB server and the web server and I still get the problem. When I try to run the universal device poller and get two errors. 1: "An item with the same key has already been added" when I click okay I get 2: " cannot contact server. exiting application" the universal device poller then closes. All services say they are running and I see no other errors. Any ideas or suggestions to resolve this would be appreciated
