      I upgraded one server in a 6-server 2.0.1 replicaSet to test MongoDB 2.2.0-rc1. I wanted to test read and locking performance so I switched to a db with a very large collection that easily exceeds RAM. I then ran a query that I knew would match no records: db.collection.find(

      {x: 1}

      ). This caused the mongostat I was running in another window to stop responding, I could connect with another shell but "show dbs" would not return until the above query completed. Also, hitting Ctrl-C on the find() query caused "Fri Aug 17 19:07:19 Assertion: 13111:field not found, expected type 2" in the shell. I was unable to manually kill the find() operation.

      I also tried this a second time so I could be sure that as much of the database that could be hot in memory was available.
