When I start the Policy Server, it stop immediately and I can see in the Policy Server logs :
Error : Failed to create main reactor
How can I fix it ?
The main reactor is responsible to receive the Agent connections and thus it needs the internal loopback address.
To solve the issue check that the addresss :
is defined in the hosts file or at least in DNS. If defined in the hosts file, be sure that the files has permissions for the smuser to read it.
