Environment

VMware SDDC Manager 5.2.x

Cause

The vcf-commonsvcs microservice has exhausted its allocated Java heap space (Xmx). This prevents the service from initializing correctly or handling inventory requests, leading to the UI hang or NGINX reporting a 502 Bad Gateway.

Resolution

1. Restart all SDDC Manager services to ensure synchronization: /opt/vmware/vcf/operationsmanager/scripts/cli/sddcmanager_restart_services.sh
2. Restart the commonsvcs service again: systemctl restart commonsvcs

If the above steps fails to resolve the issue, please log a case with Broadcom Support.

Additional Information

Monitor the commonsvcs.out log to ensure no new OutOfMemoryError messages appear and verify that the SDDC Manager UI loads the dashboard successfully.
