      Engineering Description
      When restoring database views by using mongorestore command with `--preserveUUID --drop` options, mongorestore command hangs.

      + mongo --quiet --eval 'db.version()'
4.2.3
+ mongo --quiet --eval 'db.createView("view", "coll",   [ { $project: {"field1": 1 } } ] )' test
{ "ok" : 1 }
+ mongodump --archive
