On around 21 July, we started seeing serverless failures across various driver teams.

For tests that were sending the following form of failCommand:

      "failPoint": {
        "configureFailPoint": "failCommand",
        "mode": {
          "times": 1
        },
        "data": {
          "failCommands": [
            "aggregate"
          ],
          "closeConnection": true
        }
      },

We are now getting an error code of 8000, which is not one of our known retryable error codes.
