Presto RAM: memory is growing and not falling, it is at its peak

[tolstykh-da]

Good afternoon, we are seeing a memory leak in our trino cluster (25 servers of 125gb ram each) (memory is growing and not falling, it is at its peak). The cluster is currently running with -Xmx100G,query.max-total-memory-per-node=70G,query.max-memory-per-node=60G,query.max-memory=2500GB. Tell me please, what can aliat to such behavior of RAM?
