Issue:
After implementing the Univiewer for Dollar Universe Central License (DUAS_H)  in UVMS, UVMS uses all available CPU Time, and the number of threads eventually reaches the limit. 
Response Times are really bad and makes UVC usage almost impossible.
Environment:
UVMS 6.8.01 or superior with a Centralized DUAS License (DUAS_H)
Cause:
When UVMS uses central Dollar Universe license with high number of nodes (more than 100), UVMS consumes lot of cpu and response time is abnormally high, this was due to a database request made too frequently.
Resolution:
Update to the fix version listed below or a newer version if available.

Fix Status: Released 3th July 2018

Fix Version(s):
Component: Application.Server and Univiewer.Management.Server
Version: Dollar.Universe 6.9.21
