Hello,

          I have deployed a new server for our engine using engine-backup to backup and restore to a clean system. We now get errors

ETL service sampling has encountered an error. Please consult the service log for more details.

ETL service aggregation to hourly tables has encountered an error. Please consult the service log for more details.

and in /var/log/ovirt-engine-dwh/ovirt-engine-dwhd.log

errors such as

java.lang.OutOfMemoryError: Java heap space

Exception in component tJDBCInput_9
org.postgresql.util.PSQLException: Ran out of memory retrieving query results.

Regards,
