VCO pods restarting frequently

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

VCO pods restarting frequently with error terminated. Exit code 137

 

Environment

Aria Automation 8.18

Cause

This issue occurs due to a memory leak where a HashMap is retaining over 80% of the JVM heap. Issue was with one particular workflow triggering 2000 API calls and the payload size indicates it is running with the debuggerEnabled property set to true. As running this every minute in debug mode is likely what's preventing the memory from being reclaimed and causing memory pressure

Resolution

To resolve this, set the debuggerEnabled property set to false.

and 

Restart the vco-pod using below command:

kubectl -n prelude delete pods -l app=vco-app
