We are running UIM 9.2 with hub 9.20HF6 and robot 9.20HF7 and we are seeing a memory leak of the hub process.
A restart of the Nimsoft Service fixes the issue.
The hub memory leak was caused by robot_update-9.20HF7
Release : 9.2.0
Component : UIM - SNMPCOLLECTOR
Deployed robot_update-9.20HF9+ which is available in CA Unified Infrastructure Management Hotfix Index page
