Is this a new record? For patience 
I jump cloned to a likely unloaded system (Eram, Metropolis) and wondered if I should just re-log. Instead, I did something else for a while. And it did load, everything seems normal now.
Your client has waited 15 minutes for a remote call to complete.
This could mean that the server is very loaded.Please be patient, chances are that the call will complete eventually but depending on the load it might be considerable time.
