memory leak in hub process

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)
• CA Unified Infrastructure Management On-Premise (Nimsoft / UIM)
• CA Unified Infrastructure Management SaaS (Nimsoft / UIM)

Issue/Introduction

• DX UIM Hub processes experience continuous memory growth, potentially leading to system unresponsiveness or Out-of-Memory (OOM) conditions
  
  
• This behavior is primarily observed in Secure Hub.  It does exist but to a far lesser extent in the standard hub builds.

Environment

• DX Unified Infrastructure Management (UIM) prior to 23.4.9
• Component: Hub/Secure Hub
• Version: 23.4.8.S/23.4.8 and lower
  
  
  

Cause

• A product defect (DE683976) was identified resulting in slow memory growth over time.

Resolution

• This issue will be resolved in DX UIM 23.4 Cumulative Update 9 (CU9) which will contain hub version 23.4.9/23.4.9.S.

• It is recommended to upgrade to this version or later to permanently address the leak once it becomes available (tentative ETA: End of September 2026)

• Regularly restarting the nimbus service/robot on the affected hub machine will temporarily clear the leaked memory and help mitigate the issue
