Memory bloat on concurrency - Any fix to release memory post query run

Hi, I have been using monetdb (11.25.3) in CentOS for one of application. I have been working on a PSR testing for this application and have noticed on high concurrency and on same pattern of query running again and again causing memory to bloat up and doesn’t release once the query run completes. I understand that the data is lifted into memory and the result set is also cached, however I assume this should be release once the system is idle which I don’t see it as of now. Is there any way or parameter to release the unused memory blocks? I have asked this before, but couldn't get to the root to fix this. Regards, Sreejith
