We may need a little more information about your automated install.

Part of installing torque is the initialization of the serverdb. Once 
serverdb has been created then the use of /etc/init.d/pbs_server start 
is ready to go. However,  pbs_server start is not intended to be part of 
the installation process. Can you make sure serverdb is initialized 
before you begin to use pbs_server start?
