Browsing vCenter inventory with Advanced Services -> timeout

Hi,

I'll test the newest version of vCAC. So I have create a simple Advanced Service Blueprint to create a vm snapshot (VC:VirtualMachineSnapshot) but I get a timeout notification. I think vCAC takes too Long to browse the inventory (100 Hosts, 1400VM's). How can I solve the problem? Are there any logfiles that i could search?
