This is the same issue as the 3 other posts you have so I am going to respond here. Can you send us a copy of the two pandora_server configuration files?
Can you give us more details on the database configuration and infrastructure established?
You can look for information on ha in the following webpage: [url=http://wiki.pandorafms.com/index.php?title=Pandora:Documentation_en:HA]wiki.pandorafms.com/index.php?title=Pandoraocumentation_en:HA[/url] . There you can check additional information on HA.
