Hi everyone,
I have a query about the memory usage of the Persistence Manager entry in the "Component Memory Usage" reporting under the "System Information" tab in Studio (we recently upgraded to rev 82 and there is no longer Persistence Manager but rather "System" which includes the Pool/PersistenceManager entry).
We have been trending the used memory size of this component over the past 2 weeks and it has grown (reasonably steadily) from 7GB to about 34GB. The current Column Store table memory size is about 96GB on our 512GB system. We load data from flat files using a combination of the IMPORT command and some stored procedures 3 times during the day. We are not sure why this component seems to be ever increasing. We know if we restart the services it will drop back to a few GB but then steady grow again.
Has anyone else seem this behaviour or know what might be causing this? This component is growing faster than our data volume so if left we wonder if it will approach the same used memory size as our column store tables.
Regards,
Mark.
