ucs import fails

I checked the config deeply and looks fine as you said the problem might be license related. I ve also tried to import the ucs to another box before but it failed and not accessible via GUI. ( got stuck on "Configuration Utility restarting" ) When i connect via ssh i get the error "emerg logger: Re-starting tomcat" continuously. I restarted the box several times but still getting the error. I want to try to import a previous backup usc from command line but i am not sure how can i do this on tmos. Please advice,, Thanks !!
