The server is not connected yet to internet ! One thing to mention is that when I start the AS from the console I don't have this error. It's only when I start the AS as a service. After the AS has started, the first hit to one page of the application causes a PermGen outofmemory exception. Are there differences between installation of version 5.1.0.CR1 and 5.1.0.GA ? because I simply used the same configuration for 5.1.0.CR1 in 5.1.0.GA.
