Issue/Introduction

Symptoms:
CExP appliances services fail overtime.

Environment

VMware vRealize Automation 8.4.x

Resolution

This issue is resolved in vRealize Automation 8.4.2 and vRealize Automation Cloud June 2021.

Workaround:

CExP builds newer than May 2021

1. Login via SSH to the CExP appliance
2. Run the following command to backup the set_license_flags.sh

   cp -a /opt/scripts/set_license_flags.sh /opt/scripts/set_license_flags.sh.bak
   

3. Append the set_license_flags.sh with an exit 0

   echo 'exit 0' > /opt/scripts/set_license_flags.sh

4. Remove temporary files

   find /tmp -mindepth 1 -name "tmp*" -delete || true

CExP builds older than or equal to May 2021

5. To include the above, run Kubelet is not able to reconnect to the Kubernetes API server in vRA 8.x and vRO 8.x

Note: Performance counters for CPU and memory should decrease within a few minutes of applying this workaround.
