 Description   

Lower the following WiredTiger file_manager parameters to wiredtiger_open:

  • close_handle_minimum: number of handles open before the file manager will look for handles to close. The WT default is 250. Lower to a more reasonable number like 4.
  • close_idle_time: amount of time in seconds a file handle needs to be idle before attempting to close it. The default is 28 hours. Lower to 10 seconds.
  • close_scan_interval interval in seconds at which to check for files that are inactive and close them. The WT default is 10. Lower to 5 seconds.

This will introduce more aggressive file handle sweeps.

We can add the configuration described in this ticket to the same tasks added in SERVER-41492, so closing this as a dupe.
