Netdata agent use more than 2GB ram

Hi
the netdata agent uses more than 2GB of RAM in my server. sometimes it goes to use more (near 4 GB).
I don’t know how can I fix it.
this the config

[global]
  
  hostname =chKeeper01
  dbengine multihost disk space = 2048
  SEND_SLACK="YES"
    # default storage size - increase for longer data retention
  page cache size = 32```
