To determine if you are hitting this particular issue you will need to query the vCO database vmo_clusterauditlog table to see if there are any workflow execution runs that have generated a large amount of audit logs.
Note: before proceeding take a snapshot of the vRO appliance(s).
1. SSH to the vRealize Orchestrator appliance and login as root user.
2. To connect to the vCO database:
vracli dev psql vco-db
Type yes when prompted.
3. To count audit logs per workflow run execute the select query:
SELECT COUNT(eventdata) AS occurrences, eventdata FROM vmo_clusterauditlog GROUP BY eventdata ORDER BY COUNT(eventdata) DESC;
4. If the count returned for any workflow execution id is higher than 10,000 consider removing them:
DELETE FROM vmo_clusterauditlog WHERE eventdata IN ('execution-id-1', 'execution-id-2', ...);
Replace execution-id-1 & execution-id-2 with the id's identified in step 3
If you see out of memory errors but no high count returned from query 3 above then consider increasing the default vRealize Orchestrator Java heap memory
