Yes, we have a frontend with Sunstone and OpenNebula (using NFS to share 
the common storage).

Everything becomes unresponsive, but not at the same time.
When a user performs a large batch operation, the same user can't run

After some time, users can't log into Sunstone and other services (such 
as OCCI) become unresponsive too.
